-
Natural rubber is epoxidized with peracetic acid. When epoxy group is introduced into the double bonds of the main molecular chain, the molecular polarity is enhanced,while the high elongation character remains essentially. The glass transition temperature,oil resistance,air tightness and adhesion increase significantly,but the impact elasticity decreases.Its applicability approaches to those of certain special synthetic rubbers,thus the application scope of natural rubber is broadened.
