Ethylene glycidylmethacrylate

Since a major weakness of PPS is its brittleness, some attempts have been made to improve its toughness by blending with other suitable polymers. A commercial impact modified PPS (Toray) is believed to consist of a blend of PPS with ethylene-glycidylmethacrylate polymer. A grafting reaction is expected to occur if the PPS has active end groups such as -SH or -S Na+, which can in principle react with the epoxy group of the ethylene/GMA copolymer.

These multicomponent PP blends have been developed during the last ten years. For example, they comprise (1) either an acidified-PP, its mixture with PP, or a mixture of PP with carboxylic acid-modified EPR (2) poly(methylmethacrylate-co-styrene-co-maleic anhydride) and (3) either ethylene-methylmethacrylate-glycidylmethacrylate, or ethylene-vinylacetate-glycidylmethacrylate. The compatibilization is obtained by chemical reactions between the acid and epoxy groups, as well as by forming ionic clusters capable of forming thermoreversible crosslinks. The blends were used to mold car bumpers and fenders. The products showed good stiffness and low-temperature impact resistance [8].
