    摘要： 1. A primer composition composed of 1 to 100 parts by weight of a chlorinated carboxyl group-containing a-olefin polymer and 100 parts by weight of an organic solvent therefor, the improvement wherein (i) said chlorinated carboxyl group-containing a-olefin polymer is a post-chlorination product [C] of a graft-modified propylene polymer [B] having a chlorine content of 10 to 35% by weight, said graft-modified propylene polymer [B] having an acid value of 6 to 187 mg-KOH/g-polymer and obtained by grafting an unsaturated dicarboxylic acid anhydride to a propylene polymer [A] having an intrinsic viscosity [η], determined at 135°C in decalin, of 0.6 to 10 dl/g and comprising 70 to 100 mole% of propylene and 0 to 30 mole% of an a-olefin other than propylene, and (ii) said solvent is an organic solvent boiling at about 60° to about 200 °C.

    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.

    摘要： A graft-modified copolymer having a melt flow rate of 0.01 to 100 g/10 min at a temperature of 230°C under a load of 2160g. The graft-modified copolymer is prepared by grafting (a) 100 parts by weight of low cristalline or amorphous ethylene-alpha-olefin copolymer having an ethylene content of 40 to 93 mole%, a melt flow rate of 0.1 to 50 g/10 min at a temperature of 230°C under a load of 2160 g, and a density of 0.90 g/cm³ or less with (b) 0.3 to 50 parts by weight of a styrene-type hydrocarbon. This graft-modified copolymer is suitable for use as a compounding agent for improving the impact resistance of styrene-type polymers without decreasing the surface hardness, weathering resistance, and molding properties thereof.
