Title:
4-METHYL-1-PENTENE-BASED POLYMER COMPOSITION, AND LAMINATE AND ADHESIVE USING THE SAME
Document Type and Number:
Japanese Patent JP3721265
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain an adhesive composition not only strongly adhering to a resin layer having a polar group but also excellent in heat resistance, especially the one manifesting excellent adhesion to both of a 4-methyl-1-pentene- based polymer layer and the resin layer having the polar group, and further to provide a laminate excellent in interlaminar adhesion by using the adhesive composition.
SOLUTION: This 4-methyl-1-pentene-based polymer composition consists of (A) 25-95 wt.% 4-methyl-1-pentene-based polymer and (B) 5-75 wt.% modified polyolefin-based resin comprising a mixture of (B-1) an α-olefin-based polymer obtained by using the α-olefin selected from propylene, butene-1 and 4-methyl-1- pentene and modified by an unsaturated carboxylic acid, and (B-2) an ethylene-α- olefin copolymer modified by an unsaturated carboxylic acid.
