Abstract:
1. An adhesive composition comprising: A) a first copolymer comprising 85 to 99 wt % butene-1 and 1 to 15 wt % propylene; B) a second copolymer comprising 45 to 85 wt % ethylene and 15 to 55 wt % of a comonomer selected from butene-1, hexene-1 or octene-1; C) 2 to 20 wt % of a polyolefin grafted with an ethylenically unsaturated carboxylic acid or acid derivative; and D) 20 to 93 wt % of an olefin polymer resin different from components A), B), and C), wherein the sum of the first and second copolymers is 5 to 60 wt % based on the amount of adhesive composition and the weight ratio of the first copolymer to the second copolymer is 0.3 to 3.
