POLYMER COMPOSITION AND ITS MOLDING

Japanese Patent JP2022174020

A

To provide a polymer composition capable of reducing occurrence of a foreign matter in an extrusion process and excellent in transparency and cycle characteristics, in a recycled composition of multilayer packages using a nonpolar polymer such as polyolefins and a barrier polar polymer such as an ethylene-vinyl alcohol-based copolymer.SOLUTION: A polymer composition comprises, relative to 100 pts.mass of a polyolefin-based polymer (a), at least one polar polymer (b) selected from an ethylene-vinyl alcohol copolymer (b1) and a polyamide polymer (b2) in an amount of 0.1 to 20 pts.mass, and acid modified polyolefin (d) in an amount of 0.1 to 25 pts.mass. The acid-modified polyolefin (d) is a modified ethylene copolymer obtained by modifying a copolymer of an ethylene monomer and one or two or more of α-olefine monomers of 4 to 8 carbon atoms with unsaturated carboxylic acid and/or its anhydride, and the melt flow rate of the modified ethylene copolymer (MFR: 190°C, 2.16 kg) is 15 to 39 g/10 minutes.SELECTED DRAWING: None

JPH0819294
