Abstract

PURPOSE: To obtain a modified copolymer having good adhesive and reforming properties, by graft-polymerizing an unsaturated organic acid (or derivative thereof) to an unsaturated copolymer composed of α-olefin and 1,4-diene.
CONSTITUTION: An unsaturated organic acid (or derivative thereof) such as (meth)acrylic acid or maleic anhydride is mixed with an unsaturated copolymer of a C2W12 α-olefin (e.g. ethylene or propylene) with a 1,4-diene of the formula (wherein R1 is an 8C or lower alkyl group; R2 and R3 are H, or 8C or lower alkyl group) such as a mixture of 4-methyl-1,4-hexadiene and 5-methyl-1,4-hexadiene containing 0.05W50mol% 1,4-diene, and of a modulus of elasticity 500W 80,000kg/cm2 (JIS K-7203) with a ratio of 0,0001W50pts.wt. to 1,000pts.wt. copolymer to graft-polymerize, and the resulting graft copolymer is improved in adhesive properties.
