Plenary announcement 2018 - Copy.jpg

Philip Costanzo, Ph.D.

Professor, Department of Chemistry and Biochemistry
California Polytechnic State University
San Luis Obispo, CA 93407-04


Speaker Bio:

Prof. Costanzo graduated from Carnegie Mellon University in 2001 with a BS in Chemistry. As an undergraduate, he worked for Prof. Krzysztof Matyjaszewski for three years preparing materials via Atom Transfer Radical Polymerization. He then received his Ph.D. in organic chemistry from Timothy Patten at University of California at Davis, where he focused upon polymer and nanoparticle synthesis. He was awarded a National Research Council Postdoctoral fellowship at the Army Research Laboratory. As a post-doc, he worked in the weapons and materials division developing new materials for wide range of applications. He joined California Polytechnic State University in 2007 and is currently a Professor. His research focuses upon the development of structure-property relationships by exploiting simple and efficient methodology, such as Diels-Alder chemistry, to create dynamic and stimuli-responsive materials.

Abstract:  Incorporating Diels-Alder Chemistry to Prepare Thermally-responsive Materials
Diels-Alder (DA) chemistry is becoming increasing popular due to its simplicity and efficiency. It also imparts a thermo-responsive aspect which can result in the preparation of responsive materials. The versatility of the DA chemistry allows it to be incorporated with a plethora of synthetic strategies for a range of potential applications. This work will describe the development of several different strategies of incorporation of DA chemistry within polymeric materials, including functional surfaces and prepolymers, initiators, inimers and crosslinkers and post-polymerization modification. Potential applications range from dynamic surface treatments to rehealable coatings to rheological modifiers to processable matrix resins


Dean Webster, Ph.D.

2018 Keynote SPEAKER

Speaker Bio:Dean Webster is Professor and Chair in the Department of Coatings and Polymeric Materials at North Dakota State University. He received a B.S. in Chemistry and a Ph.D. in Materials Engineering Science both from Virginia Tech.  Prior to joining NDSU in 2001 he worked for Sherwin-Williams and at Eastman Chemical Company.  He is the recipient of the 2011 Roy W. Tess Award in Coatings Science given by the American Chemical Society,the 2013 Joesph Mattiello Lecture award given by the American Coatings Association, and the Waldron Research Award given by the NDSU Alumni Association. He was named Fellow of the American Chemical Society in 2016. His research is in the area of new high performance polymer systems for coatings and composites, nanocomposites, polymers for marine antifouling coatings, and use of renewable resources in polymers and coatings systems.

Abstract: Sustainable Thermosets from High Functionality Bio-based Resins

A challenge faced in transitioning from polymer materials derived from petrochemical sources to bio-based sources is in designing materials having the performance properties required for today’s demanding applications. Thermosetting resin systems are used in numerous high performance coating systems. While vegetable oils are a readily available and amenable to functionalization to be used in thermosets, their long aliphatic hydrocarbon chains tend to result in materials that are soft and flexible. However, we have found that by creating multifunctional resins from vegetable oil fatty acids and a highly functional polyol, thermosets can be formed that have the strength and stiffness for use in high performance applications. For example, epoxidized sucrose esters of vegetable oil fatty acids, such as epoxidized sucrose soyate (ESS, Figure 1) crosslinked with cyclic anhydrides yield thermosets having high modulus, solvent resistance, and hardness. Polyurethanes made using highly functional soy polyols have glass transition temperatures exceeding 100 °C, much higher than typical soy-based polyols. In addition, 100% bio-based thermosets can be made from the water-catalyzed crosslinking of epoxidized sucrose soyate with naturally-occurring acids such as citric or tartaric acids. Further functionalization with acrylate or methacrylate groups can lead to systems cured using free radical photopolymerization and via Michael reaction chemistry. We have also discovered a process for synthesizing highly functionalized lignin that can be cured into hard and durable coatings. In all of these examples, the thermosets formed have properties superior to their triglyceride oil counterparts and equivalent to current petrochemical resins.

The Sidney Lauren Memorial Lecture


Don graduated with a BS in Chemistry from Wayne State University in Detroit in 1984 and joined BASF Automotive Coatings.  He has worked in both resin development and topcoat development including basecoat, clearcoat and 3-wet systems.  With his experience managing clearcoat service for more than 15 paint lines, Don is now moving to a role as Intellectual Property Manager.  After 32 years with BASF, he has 32 patents and has published numerous articles.


The practice of calculating the crosslink density of a polymer network has been described by numerous authors going back to Flory. In most cases, the format for the calculations is based on a derivation. This can make the calculations quite difficult, and in some cases, terms are reused referring to both the prepolymer constants and those of the final network. We have reformatted these calculations into a more intuitive process based on prepolymer constants that are familiar to coatings chemists. We  emonstrate the equivalence of these calculations to those of previous authors for various degrees of prepolymer functionality in a condensation cross link reaction. Crosslink density measurements are presented to validate the effect of prepolymer degree of functionality that has been questioned by some. We also apply these methods to ultraviolet light cured systems and derive the relationship between kinetic chain length and crosslink density for several acrylate oligomers.
