Title:
変性ポリオレフィン樹脂
Document Type and Number:
Japanese Patent JP7175183
Kind Code:
B2
Abstract:
A modified polyolefin resin having an intended adhesion strength to various substrates even when graft modification may be carried out by using an α,β-unsaturated carboxylic acid derivative having a cyclic structure. The modified polyolefin resin may be a modified product of a polyolefin resin and satisfies conditions (A) to (C): condition (A)—a modifying component includes an α,β-unsaturated carboxylic acid derivative having a cyclic structure; condition (B)—a ring-opening degree expressed by formula (1) is 40 or more; and condition (C)—the polyolefin resin includes an ethylene structural unit,ring-opening degree=modification degree K×ring-opening rate R (1)wherein, in the formula (1), the modification degree K is a grafting weight (wt. %) of the α,β-unsaturated carboxylic acid derivative, and the ring-opening rate R is a ring-opening rate (%) of the cyclic structure in the α,β-unsaturated carboxylic acid derivative.
