    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.

    摘要： A stretched film of polypropylene which is excellent in transparency, substantially free of an antiblocking agent and at least uniaxialy stretched and which is characterized in that it has uniformly distributed projections having a height ranging from 0.05 to 0.50 µ and a width ranging from 10 to 100 µ at least on the surface thereof as well as a method for preparing the foregoing stretched film of polypropylene which comprises the steps of forming, into a sheet, polypropylene which comprises a nucleating agent in an amount selected so that the crystallization temperature of polypropylene is increased by 1 to 10°C by the addition thereof and then stretching the sheet at a temperature ranging from 140 to 165 °C are herein disclosed.
