The stabilization medicine for the polyolefine type resin and the polyolefine type resin composition which is stabilized

摘要

This invention, the polypropylene type resin (the PP resin) being something which offers the PP resin composition which possesses the high-level stability which the stabilization medicine and the said stabilization medicine which can grant high-level heatproof stability is added, the ethylene characteristic unsaturated monomer which has the piperijiru basis inside the molecule below-mentioned general formula (i) (a) the alkyl where 1 - 50 mass sections and isobuchirumetakurireto and carbon count have the alkyl group of 6 - 13 (at least the monomer of 1 where it is chosen from meta) acrylate and the aromatic vinyl monomer kinds (b) 50 - 99 mass sections and, (a) and (b) the ethylene characteristic unsaturated monomer other than(C) 0 - 20 mass sections (however, (as for a), (b) and (c) total 100 mass sections) the copolymer which is obtained by the fact that the unsaturated monomer blend which consists of is polymerized the stabilization medicine which (A) is contained is used.(As for R^{1 the} hydrogen atom or carbon count the alkyl group of 1 - 2, as for X the oxygen atom or the imino basis, as for Y the hydrogen atom or carbon count alkyl group or the arukokishiru basis 1 - 20, as for Z the hydrogen atom or the cyano basis is shown.)
