摘要：
A modified polyolefin composition comprising
(A) 50 to 99 parts by weight of a modified polyolefin having an intrinsic viscosity [η] of 0.5 to 10 dl/g and a degree of crystallization of at least 20% selected from the group consisting of polyolefins modified with styrene-type hydrocarbons, polyolefins modified with unsaturated epoxy compounds, polyolefins modified with unsaturated silane compounds, halogenated polyolefins and hydroxyl group-containing polyolefins, and
(B) 1 to 50 parts by weight of a thermoplastic polymer selected from the group consisting of
(B-1) thermoplastic polymers having a flexural modulus of less than 100 kg/cm 2 , a glass transition temperature (Tg) of not higher than 0°C and a weight average molecular weight (Mw) of at least 400,000, and
(B-2) polar non-olefinic thermoplastic polymers or ethylenic polymers having a flexural modulus of at least 1000 kg/cm 2 and an adhesion strength, with respect to the modified polyolefin (A), of not more than 200 g/cm. The above composition is useful as an adhesive.
