Title:
RESIN COMPOSITION FOR MASTERBATCHES
Document Type and Number:
WIPO Patent Application WO/2019/172355
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a masterbatch of a liquid additive which can contain the liquid additive at an increased concentration, is less sticky, and is easy to handle. Additionally, the present invention addresses the problem of providing: a resin composition that has excellent slidability and wear resistance without a deterioration in the conventional mechanical properties and moldability of engineering plastics; and a molded body. The present invention uses a resin composition for masterbatches which contains: (a) a block copolymer containing polymer blocks mainly composed of a vinyl aromatic compound and polymer blocks mainly composed of a conjugate diene compound, or a hydrogenated product thereof; 40 to 100 parts by mass of a polyolefin resin relative to 100 parts by mass of the component (a); and 100 to 150 parts by mass of an ethylene-α-olefin copolymer having a dynamic viscosity at 100ºC of 10-5000 mm 2/s, a molar ethylene content of 30-85 mol%, and a molecular weight distribution (Mw/Mn) of polystyrene-equivalent molecular weights determined by gel permeation chromatography (GPC) of 2.5 or less.
