ABSTRACT:
A material which exhibits enhanced mechanical strength and heat resistance is provided, comprising: (a) 99.9 to 60% by weight of a modified polyolefin or a polyolefin containing such a modified polyolefin in an amount of at least 1% by weight, the modified polyolefin having a copolymer portion as a graft or a block in a polyolefin, the copolymer portion made of an unsaturated carboxylic acid or a derivative thereof and a monomer, which has a monomer reactivity ratio, the product of which, when multiplied by a monomer reactivity ratio of the unsaturated carboxylic acid or the derivative thereof, is 1 or less; and (b) 0.1 to 40% by weight of a lipophilic interstratified compound in which tetraalkylammonium cation is inserted in a swellable stratiform silicate; can be obtained simply by taking the steps of mixing and melt-kneading in the absence of a solvent, without swelling and cleaving a stratiform silicate compound using a swelling/dispersing medium or the like, such as an organic solvent.
