GRANULAR STABILIZER FOR POLYMER AND PRODUCTION PROCESS THEREOF

摘要

PURPOSE: A granular stabilizer for a polymer is provided to be easily handled because of a small amount of dusting and to have excellent dispersity while having excellent blocking resistance. CONSTITUTION: A granular composition comprises 99.9-80 weight% of a compound represented by chemical formula 1 and 0.1-20 weight% of a compound represented by chemical formula 2 based on 100 weight% of the granular composition. The melting point of the compound represented by chemical formula 1 is 100-140°C and the melting point of the compound represented by chemical formula 2 is 30-80°C. The compound represented by chemical formula 1 is one or more compounds selected from 2-[1-(2-hydroxy-3,5-di-t-pentylphenyl)ethyl]-4,6-di-t-pentylphenyl acrylate or 2-t-butyl-6-(3-t-butyl-2-hydroxy-5-methylbenzyl)-4-methylphenyl acrylate.
