Practical Tips for Curing Thermosets Part Two: Impact of Cure Temperature on the Glass Transition Temperature

September 19, 2016 By Jeffrey Gotro Leave a Comment

In the previous post we reviewed the concept of vitrification during thermoset curing.  In this post we will give some examples of how the cure temperature can impact the degree of cure and the glass transition temperature during processing.  In the first case, we will consider the curing of a two part epoxy-amine system at 80oC. If the goal was to get a Tg as high as ... [Click to Continue...]

Practical Tips for Curing Thermosets Part One: Review of Gelation and Vitrification

September 12, 2016 By Jeffrey Gotro Leave a Comment

In some of our previous posts we discussed the concepts of gelation and vitrification during thermoset curing. In this series of posts we are going to give some practical examples of how gelation and vitrification impact thermoset curing.  Thermosets are unique in that during processing a chemical reaction (curing) transforms small molecules into a large crosslinked network. ...

Renewable Polystyrene and PET: Part 4

August 29, 2016 By Jeffrey Gotro Leave a Comment

Guest Post by Dr. Robert Humphreys As explained in previous posts, most plant biomass (about 80% by weight) consists of carbohydrates (cellulose and hemicellulose), biopolymers that are rich in oxygen. In contrast, petroleum is comparatively rich in hydrogen and contains very little oxygen (usually less than 1% by weight, often much less). Figure 1 shows the structure of ... [Click to Continue...]

Renewable Polystyrene and PET: Part 3

August 22, 2016 By Jeffrey Gotro 74 Comments

Guest Post by Dr. Robert Humphreys This post will focus on technologies for conversion of biomass to renewable BTX as a source of renewable polystyrene (PS) and polyethylene terephthalate (PET), as well as many other valuable polymers and chemicals that are so much a part of life in the modern world (Figure 1). Many initiatives have focused on developing renewable BTX, ... [Click to Continue...]

Polymer Innovation Blog

I’m Dr. Jeff Gotro and welcome to the Polymer Innovation Blog. Over the last 40 years I have been involved in polymer research, along with product and process development. I acquired invaluable experience working for IBM, AlliedSignal, Honeywell, Ablestik Labs (now Henkel) and in multiple consulting projects. In this blog, I (along with some guest contributors) will share our experiences, tips, and “tricks of the trade” to get more out of your innovation efforts and discuss new trends and technical advances in the polymer industry.
