Thermoplastic resin composition.

摘要

A thermoplastic resin is stabilized by incorporating therein a dinitrodiamine compound represented by the formula of <CHEM> wherein X is a divalent aliphatic, alicyclic or aromatic group which may contain halogen or oxygen in the group, R<1> is hydrogen or an aliphatic, alicyclic or aromatic group, provided that two nitrogen atoms linking through X may further link through R<1> when both X and R<1> are the aliphatic groups, and R<2> and R<3> independently of one another are each hydrogen or an alkyl of 1 to 12 carbon atoms, provided that R<2> and R<3> may conjointly form a ring. The composition thus blended is improved in thermal processing stability. Further, a modified polyolefin resin is improved in mechanical properties, particularly in impact strength, by the incorporation of the dinitrodiamine compound.
