NUCLEATOR MASTERBATCH FOR POLYOLEFIN RESIN

摘要

Disclosed is a nucleator masterbatch for polyolefin resins, which is excellent in dispersibility in polyolefin resins and resistance to thermal coloration. This nucleator masterbatch for polyolefin resins enables to improve transparency and mechanical strength of a polyolefin resin which is a crystalline polymer. Also disclosed is a polyolefin resin composition using such a nucleator masterbatch for polyolefin resins. Specifically disclosed is a nucleator masterbatch for polyolefin resins, which is characterized by being obtained by adding 3-150 parts by mass of an aromatic metal phosphate salt represented by the general formula (1) below to 100 parts by mass of a completely hydrogenated petroleum resin having a softening point of not less than 100°C.
