Title:
POLYMER COMPOSITION AND MOLDED ARTICLE THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/239729
Kind Code:
A1
Abstract:
A polymer composition that comprises, relative to 100 parts by mass of a polyolefin-based polymer (a), 0.1-20 parts by mass of at least one polar polymer (b) selected from an ethylene-vinyl alcohol-based copolymer (b1) and a polyamide-based polymer (b2) and 0.1-25 parts by mass of an acid-modified polyolefin (d). The acid-modified polyolefin (d) is a modified ethylene copolymer obtained by modifying a copolymer, said copolymer comprising an ethylene monomer and one or more α-olefin monomers having 4-8 carbon atoms, with an unsaturated carboxylic acid and/or an anhydride thereof. The melt flow rate (MFR: 190°C, 2.16 kg) of the modified ethylene copolymer is 15-39 g/10 min.
