Thoi was the finest gentleman I will ever have the chance to work with while in DOW PC and PE businesses. I will never forget that smiling face. It turned out that I partnered with Thoi on projects where the answer is always needed yesterday. But his smiling face and calming words seemed to make everything work out at the end.

Life is as fragile and we lost Thoi in our journey together.

Thoi had many friends at Sumitomo Chemical throughout the years. I was one that enjoyed his many stories about his travels and about good food. Thoi always had a notable smile just before starting an extra interesting or funny story. His willingness to share knowledge was constant. And working with Thoi on technical items was often challenging and insightful.

We send our condolences to the family and wish his spirit eternal peace.

Although we know that life is fragile, and can throw a curved ball now and then, the news of Thoi's passing was completely out of the blue. Certainly, we were shocked, but more so we were deeply saddened. We remember Thoi as a good-natured person, who enjoyed life with family and friends. His exuberance for sharing knowledge and experiences endeared him to all who knew him. May God bless his soul. Our warmest condolences to Chi Lang and family.

I was shocked to learn of Thoi’s tragic and untimely death. I can only imagine what Lang, Thai, Van and all of Thoi’s extended family must be going through trying to make sense of a senseless death. I extend my deepest sympathies to each of you!

I worked with Thoi off and on through much of my Dow career. We both had an interest in polymer stabilization—me more on the degradation chemistry side, he more on the organic chemistry side of stabilization. When he left Polycarbonate Research and came to Polyolefins Research, we worked closely together, eventually as co-inventors on patents. We didn’t always agree, which led to many hours of fruitful discussion, trying to win each other to our point of view! Somewhere in those discussions, the truth would generally emerge, and we gained respect for each other. I was happy when I returned to Dow from DDE in 2006 to be able to work with Thoi again for a couple years.
Thoi was well respected in the technical community both within Dow and in the larger plastics industry, where he actively engaged scientists throughout the plastics additives field as an active participant in SPE conferences and activities. He will be missed.

As important as that role was, though, his roles as husband, father and grandfather were more important, and I know that he will be missed by his family even more than his colleagues. I pray that they will be comforted.

Thoi, we miss you my friend. I will always remember the lively discussions we had on various technical topics. I learned a lot from you in Organic Chemistry and I really enjoyed your keen interest in getting in depth understanding of Polymer Physics from me.

I will always remember you walking to my office with a curious smile on your face. I immediately knew that you have some ideas that you want to discuss with me. I really appreciated that.

Your absence will always be missed as we continue on various technical projects that we initiated with you.

And of course, your collection of dark chocolates from various countries will be missed.

So sad to hear of Thoi’s passing. All I have are good memories of working together with him at Dow. He and I started working there in the same group at about the same time and I followed him through the company until he retired. He was a good friend and mentor always ready to help, friendly, and full of joy. I have many fond memories of working with Thoi on projects at Dow and going on trips together. My prayers go out to Lang and the boys and their families; I know he will be missed.

Friends are kind; they share; they mentor; they help. Thoi had always led the Lake Jackson pack with these attributes and so much more. We have known Thoi for many years and, through this time, our families have grown together and shared many memories. We will never forget his legendary crawfish boils or exploring different cities on business trips. Thoi had always been the first to introduce new activities to our circle - acting as a true leader. He always shared with no hesitancy and we could always count on him for this. Not only is Thoi a long lasting friend to us, but a role model and confidante for many others.

Although he departs this earth, he still lives on in our minds and thoughts, and through that he lives on. We know that he will be remembered and cherished with many fond memories, but for us, we will remember him as a true, loving, and caring friend.

I was devastated to hear of his passing. I retired 2.5years ago from Flint Hills Resources and I am grateful to Bill and Nick to have informed me.
My best memories of Thoi are the time I spent with him teaching how to use the multiple software systems we had to utilize every day. He was always so attentive and taking notes.
It was an honor for me to have met him and learning the basic chemistry of polymer stabilization. We shared my knowledge of plastics processing.
Thoi was so proud of his Family

My husband Daniel and Thoi always had interesting conversations during technical team dinners and events.

You will be missed....

I am so sorry for the loss of Thoi particularly, so suddenly.

Thoi was a regular in the microwave line at lunch. He always had some subject to chat about. We had a lot of commonalities since we had both come from the Houston area to come to work at FHR Longview after retirement from previous companies.

We enjoyed time together in the swim aerobics class and lap pool at the Institute for Healthy Living . Thoi and his wife both were doing swim exercise.

Woodie, the swim leader, was always trying to get us to a cohesive group with her counting the exercises in all the foreign languages of our class members. Vietnamese was definitely a challenge.

I was devastated to learn about the loss of Thoi. We have known each other for decades... Looking back, it was always fun working together back in the days of Dow & Ciba-Geigy... Lots of fond memories. I also enjoyed working with Thoi regarding the International Polyolefins Conference. Thoi and I worked together every year; he needed speakers, and I was always happy to be part of his technical session. Thoi's relentless commitment to make the Technical Sessions a success was always impressive. His volunteer work for SPE was most noteworthy; especially the tutorial sessions on Sunday... a lot of extra work, but something that helped the early in career folks in our industry.

I will miss Thoi, his intensity, his curiosity, his smile...

Please take care... All my best wishes... All my sympathy...

Rick King (BASF)... your friend, and your scientific colleague
