Summary of Expertise:

Primary Expertise Areas: (links show more experts in each area)	Expertise Description:
anionic polymerization expert ionic polymerization expert	Expert is an expert in not only free radical polymerization but cationic and anionic polymerization as well. He has several patents and scientific papers on ionic polymerizations.
chain transfer expert chain transfer agent expert	Expert has expertise in chain transfer chemistry operative during vinyl polymerization. He is very knowledgeable in the chain transfer chemistry of both free radical and anionic polymerization of vinyl monomers. He was an early pioneer of the development of chain transfer agents that operate by the addition-fragmentation mechanism.
free radical polymerization expert living polymerization expert nitroxide expert initiation expert	Expert notes that monomers must undergo and initiation step before polymerization can take place. He has performed detailed studies to determine the mechanism of polymerization of vinyl monomers. He has published several scientific papers on this subject. He is a well-known expert on free radical polymerization as well as on living or controlled radical polymerization. He was one of the early pioneers in developing an understanding of living radical polymerization and holds several patents on this area of technology.
polymer chemistry expert synthetic polymer chemistry expert polymer modification chemistry expert	Expert holds a Ph.D. in synthetic organic chemistry and has applied this knowledge to polymers. He also has expertise in polymer analysis, and has authored about 100 publications in scientific journals, most of which are in the area of polymer chemistry and polymer analysis. In 2001 Expert was made "Fellow" of the Polymeric Materials Division of the American Chemical Society for his key accomplishments in polymer chemistry.
polystyrene degradation expert	Expert is considered to be a world-class expert in the field of polymer stabilization and degradation. His approach to polymer degradation research has not been Edisonian (running hundreds of experiments), but rather he first tears degraded polymers apart in order to fully understand degradation mechanisms. Once the mechanism of degradation is determined, he conducts focused experiments to demonstrate problem resolution. He holds several patents and many publications in this field.
styrene expert	Expert has an in-depth understanding of the chemistry of styrene and of all the trace impurities it contains. He also is an expert in purification of styrene and also on stabilizing it against polymerization.
acrylonitrile butadiene styrene resin expert	Expert is an expert on ABS plastics, including failure mechanisms, degradation, stabilization, and discoloration.
biodegradable plastic expert biodegradable plastic film expert degradable plastic expert	Expert was an early pioneer of biodegradable polystyrene research. He developed the technology to insert hydrolyzable ester linkages into the polystyrene backbone allowing it to biodegrade. His work with the development of environmentally degradable polystyrene foam food packaging has been widely published.
bisphenol A polycarbonate expert polycarbonate expert	Expert developed state-of-the-art polymer analysis techniques that allowed him to characterize off-grade (discoloration and low strength) polycarbonate resins. His work led to a fundamental understanding of the structure/property relationships in polycarbonate plastics. He has published his pioneering work on the application of GPC-UV analysis of polycarbonate.
concurrent cationic/free radical polymerization expert	Expert is widely recognized as the top expert in the world on concurrent cationic/free radical polymerization. He has published several papers on and patented vinyl polymerizations in the presence of strong acids.
dimer expert oligomer expert	Expert notes that, generally, one desires to make a high polymer. However, some oligomers have useful properties and can be used as polymer additives; e.g., to improve rheological properties. Expert has isolated the individual dimers and studied their decomposition chemistry. He has published several papers on this pioneering work in this area.
free radical expert free radical catalyst expert free radical chemistry expert	Expert is globally recognized for his pioneering work on the development of living free radical polymerization. He holds seven patents and has authored many papers on the subject.
barrier polymer expert	Expert is an expert in polymer permeability. He has extensive experience in making new high barrier plastic films.
construction plastic material expert	Expert has significant experience with plastics used in home construction. The list of plastics includes Styrofoam* insulation board, PVC, and CPVC plumbing fittings. ®™* Trademark of The Dow Chemical Company ("Dow") or an affiliated company of Dow.
monomer analysis expert	Expert notes that polymers are generally contaminated with traces of unreacted monomer. The monomer residues can impart odor to plastics. Expert is an expert in analytical chemistry and has utilized several techniques to measure the level of residual monomers in plastics.
plastic material expert	Expert states that if it's made of plastic, he can help. He has over 30 years' experience as an inventor and problem solver in the plastics industry and as several years of experience serving as an expert witness on forensic analysis of the failure mechanisms of plastic materials.
polymer characterization expert	Expert is an expert in analytical chemistry and has published many scientific papers on polymer characterization.
polymer degradation expert polymer aging expert	Expert notes that polymer degradation (aging) is a problem with many plastic materials and that additives or stabilizers are generally added to the plastic to increase its lifetime. Expert is an expert in the chemistry of polymer aging and the selection of the right stabilizer to increase plastic lifetime. He has published many scientific papers on this subject.
polymerization inhibitor expert	Expert notes that most vinyl monomers are highly reactive and must be stabilized with a polymerization inhibitor for safe distillation, handling, and storage. He has developed new inhibitors for acrylate, methacrylate, styrenic monomers, and monomer mixtures. Expert also notes that some inhibitors must be removed before the monomer is used to make plastics; he has developed inhibitors that allow the manufacture of high quality plastics without removal.
