HYDROXY-MODIFIED ETHYLENE-amp;alpha;-OLEFIN-BASED COPOLYMER, COMPOSITION OF THE SAME AND METHOD FOR PRODUCING THE HYDROXY-MODIFIED ETHYLENE-amp;alpha;-OLEFIN-BASED COPOLYMER

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a hydroxy-modified ethylene-α-olefin-based copolymer, capable of simply and efficiently producing the copolymer, without accompanying crosslinking reaction nor degradation reaction to an ethylene-α-olefin-based copolymer used as a raw material, to provide the hydroxy-modified ethylene-α-olefin-based copolymer having excellent coating properties and adhesion, and to provide a composition of the same.;SOLUTION: This hydroxy-modified ethylene-α-olefin-based copolymer is produced by heat-treating the ethylene-α-olefin-based copolymer in the presence of a peroxide having a hydroperoxy group. The peroxide having the hydroperoxy group in an amount of 0.1-20 pts.wt. is mixed into 100 pts.wt. of the ethylene-α-olefin-based copolymer. The copolymer is heat-treated at a temperature in a range from a temperature at which a half of the peroxide is decomposed in 10 hr to another temperature at which the half of the peroxide is decomposed in 1 min.;COPYRIGHT: (C)2004,JPO&NCIPI
