High impact strength shinjiotakuteitsuku polystyrene riakutaaroi

摘要

Syndiotactic polystyrene riakutaaroi of this invention, the aromatic vinyl monomer and the rubber-like elasticity body and, and selectively, is produced polyphenylene ether by the transition metal catalyst and under co-catalyst existing polymerizing, the aforementioned reactor alloy includes, (a) syndiotactic polystyrene 50 - 99 weight %, (b) rubber-like elasticity body 1 - 50 weight %, (c) polyphenylene ether 0.1 - 10 weight % selectively. As for the reactor alloy of this invention, angular dispersion is superior styrene type monomer and in comparison with the melting blend which polymerized with the rubber-like elasticity body (b) for shocking reinforcement, boundary rigidity is high. As for the reactor alloy of this invention, shocking strength is high markedly without impairing elastic rigidity and heatproof quality by furthermore adding the polyphenylene ether (c) which is the selective component, in comparison with the melting blend of the identical content rubber component.
