乙烯基苯

This dissertation was designed to study heteto-phase grafting polymerization of vinyl acetate , maleic anhydride and VAC/MAH binary monomer system, irrespectively, with low density polyethylene film as substrate and benzophenone as photoinitiator. The purpose is to develop new and more effective methods to modify the surface and buck properties of polyolefines by studying the grafting mechanism of the system and exploring the characteristics of the grafting process.
