Patent

CA 2042744

A syndiotactic graft copolymer is here disclosed in which a radical polymerizable unsaturated compound is grafted on a propylene homopolymer or copolymer, and this graft copolymer is obtained by heating a homopolymer having a substantially syndiotactic structure of pro- pylene or a copolymer having a substantlally syndiotactic structure of propylene and another .alpha.-olefin and a radical polymerizable unsaturated compound such as an unsaturated carboxylic acid or an unsaturated silane in the presence of a radical initiator up to the decomposition tempera- ture or more of the radical initiator. This kind of graft copolymer can be used as a composition for adhe- sion. The graft copolymer in which the radical poly- merizable unsaturated compound is a hydrolyzable unsatu- rated silane can be converted into a crosslinked polymer by heating in the presence of water, and it can also be converted into a water-crosslinkable resin composition by adding various additive thereto.
