Title:
POLYOLEFIN STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2018/070194
Kind Code:
A1
Abstract:
A polyolefin structure that includes 60-97 mass% of a polyolefin (A), 1-35 mass% of an acid-modified polyolefin (B), and 2-35 mass% of a polyamide resin (C). The polyamide resin (C) is distributed as a layer in the polyolefin (A). The polyamide resin (C) is a melt-kneaded material that includes 30-70 mass% of an aliphatic polyamide (Y) and 30-70 mass% of a polyamide (X) that contains a diamine unit and a dicarboxylic acid unit (where, the total of the polyamide (Y) and the polyamide (X) is 100 mass%). The diamine unit includes at least 70 mol% of a meta-xylylene-diamine unit, and the dicarboxylic acid unit includes an α,ω-straight-chain aliphatic dicarboxylic acid unit. The difference between the melting point Tm0, as observed using differential scanning calorimetry, of the polyamide (X) and the melting point Tm1 for the polyamide (X) in the polyamide resin (C) is 0.1°C-2.5°C.
