    摘要： A method for preparing a molded article of a crosslinked polyolefin is here disclosed which comprises the steps of bringing a composition comprising a copolymer of an alkenylsilane and an olefin and a compound having at least two unsaturated bonds into contact with a catalyst selected from the group consisting of salts of rhodium, alkoxy compounds and metallocene compounds of metals in the group IVa of the periodic table, combinations of the metallocene compounds and organic metal compounds, and then molding the composition, or carrying out the contact simultaneously with the molding, or molding the composition, and then bringing the molded article into contact with the catalyst, and if necessary, further heating the molded article to accelerate a crosslinking reaction.
    The molded article of the crosslinked polyolefin obtained by the method of the present invention has a high crosslinking density and is excellent in mechanical properties, solvent resistance and heat resistance.

    摘要： 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 propylene or a copolymer having a substantially syndiotactic structure of propylene and another α-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 temperature or more of the radical initiator. This kind of graft copolymer can be used as a composition for adhesion. The graft copolymer in which the radical polymerizable unsaturated compound is a hydrolyzable unsaturated 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.
