Phase Transition Polymers
- Created a family of novel, amphoteric polymer systems exhibiting unusual "smart" properties and developed the technology for their use in numerous application areas.
- Phase transition polymers are materials that undergo significant property changes accompanying minute changes in their environment.
- Work resulted in 5 issued patents, eight pending patents and two publications. Application areas include:
- High speed photopolymer systems.
- Piezoelectric biosensors and environmental sensors.
- Gelatin substitutes in silver-based photographic media.
- Controlled capture and release systems.
- Protein separation in bioreactors.
- Recyclable and otherwise environmentally friendly systems.
Heteromphase Polymer Systems
- Created and led the development of high strength, melt processible, thermoplastic elastomers based on the ABA-gA block-graft copolymerization of dienes and lactones.
- These polymers exhibited outstanding physical properties and could be melt spun at high speed into exceptional fibers. Invented a unique dianionic initiator system useful for initiating highly elastomeric cis-1,4-diene polymerization.
- Co-developed unique thermoplastic elastomer systems having unusual hydrophilicity characteristics derived from dienes and ethylene oxide, and from isobutylene and pivalolactone.
- Work resulted in five issued patents and 10 publications.
- Work varied, but generally related to polymer physics, polymerization, solid state polymerization, heterogeneous catalysis, and in chemistry, spectroscopy and electronic theory of transition metal chelates.
