Granular stabilizer formulation and production method thereof

摘要

A granular stabilizer formulation comprising 1 to 95% by weight of (A) 3,9-bis[2-[3-(3-t-butyl-4-hydroxy-5-methylphenyl)propionyloxy]-1,1-dimethylethyl]-2,4,8,10-tetraoxaspiro[5.5]undecane and 99 to 5% by weight of (B) a compound having a hindered amine skeleton of the formula (1):
wherein, R represents a hydrogen atom or methyl group, and a method for preparing thermoplastic polymer compositions comprising 0.01 to 2 parts by weight of the granular stabilizer formulation per 100 parts by weight of thermoplastic polymer.
