Various graft copolymers have been prepared for diverse applications including material compatibilization, enhanced mechanical properties such as tensile strength, improved metal adhesion, controlled wettability, better pigment dispersion, and enhanced thermal stability. These graft copolymers were synthesized using our own patented process, viz.: 
- Solid phase process (catalytic or noncatalytic)-
U.S. Patent No. 5,079,302, January 7, 1992
U. S. Patent No. 5,510,429, April 23, 1996 - Flame initiated process-
U.S. Patent No. 5,571,869, November 5, 1996 - Supercritical fluid grafting process-
U.S. Patent No. 5,663,237, September 2, 1997
Graft copolymers successfully synthesized include PP-g-MA, PP-g-PS, PS-g-AA, PS-g-MA, PVC-g-VAc, PC-g-PMMA, PET-g-AA, and PBAT-g-MA. Most recently, we have successfully grafted MA onto PVDF, which opens great avenues for advanced material design and compatibilization. The sponsors of this research include BFGoodrich, Kimberly-Clark, Dow Chemical, Atofina, PPG Industries, Zeon Chemical, etc. For related subjects in graft copolymers, please contact us.
Our graft copolymerization technology is available for licensing from ChemTech Innovators. If you are interested in licensing one or several of these technologies or developing a tailor-made novel process for your own particular needs, please contact us. If you are interested in developing novel graft copolymers or their specialty applications, please contact us.
