POLYPROPYLENE RESIN COMPOSITION |
摘要 |
<p>2 6 The present invention relates to a polypropylene resin composition useful as an adhesive comprising (A) from about 51 wt. % to about 99 wt. % of a modified polypropylene resin graft-modified with a radical-polymerizable polar unsaturated compound or a mixture of the modified polypropylene resin graft-modified with a radical polymerizable polar unsaturated compound with an unmodified polypropylene resin, (B) a substantially non-crystalline .alpha.-olefin copolymer, and (C) an ethylene/ .alpha.-olefin copolymer having a density of from about 0.860 g/cm3 to less than about 0.910 g/cm3, a n-hexane insolubility of at least about 50 wt. % and a melting point of at least 100.degree.C, wherein the combined weights of components (B) and (C) is from about 1 wt.%. to about 49 wt. %, and the weight ratio of (B)/(C) is from about 1/99 to about 99/1. The resin composition is particularly suitable for bonding a polypropylene resin layer and an ethylene/vinyl alcohol copolymer layer, and a polypropylene resin layer and a nylon layer.</p> |
