ADHESIVE POLYPROPYLENE RESIN COMPOSITION AND MULTI-LAYER LAMINATE BODY USING THE RESIN COMPOSITION

摘要

Disclosed are (1) an adhesive polypropylene resin composition comprising (a) 50 to 90 parts by weight of a modified polypropylene or a composition containing said modified polypropylene, said modified polypropylene being graft-modified with at least one monomer selected from the group consisting of an unsaturated carboxylic acid from the group consisting of an unsaturated carboxylic acid and a derivative thereof and (b) 10 to 50 parts by weight of a modified polyolefin other than the modified polypropylene or the composition (a), said modified polyolefin being grafted with at least one monomer selected from the group consisting of an unsaturated carboxylic acid and a derivative thereof, and (2) a multi layer laminate body comprising (i) a layer of a polyolefin (ii) a layer of the above-said adhesive polypropylene resin composition and (iii) a layer of a polyamide resin and/or an ethylene/vinyl alcohol copolymer, said-layers being laminated in the order of (i), (ii) and (iii). The composition of (1) has an excellent adhesion capability for a polyolefin resin layer such as polypropylene layer and also a layer of polyamide resin and/or an ethylene/vinyl alcohol copolymer resin layers.
