Various graft copolymers have been prepared for diverse applications including material compatibilization, enhanced 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.:

The 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. The sponsors of this research include BFGoodrich, Kimberly-Clark, Dow Chemical, Zeon Chemical, etc.

Some of the highlights of our graft copolymerization technology are shown in the following figure. We have the most comprehensive grafting capabilities as well as specialized expertise in this area. Our grafting technology is protected by a number of U.S. and international patents.

"Catalytic Solid Phase Grafting of Polymers", U.S. Patent No. 5,079,302.

"Polycarbonate-g-Polyacrylate by Graft Copolymerization", U.S. Patent No. 5,510,429.

"Flame-Initiated Graft Copolymerization of Polymers", U.S. Patent No. 5,571,869.

"Graft Copolymerization in Supercritical Fluid Media", U.S. Patent No. 5,663,227.

With these patented and other proprietary processes, there is virtually no limit in our polymer grafting technlogy. Some of the successful examples in our laboratory are shown in the chart on this page.
