ABSTRACT:
A glass-reinforced polymer composition of the invention contains 80 to 99.99 parts by weight, of a 4-methyl-1-pentene polymer, 0.01 to 20 parts by weight of a graft-modified polymer of 4-methyl-1-pentene having graft units of an unsaturated carboxylic acid or an acid anhydride thereof in an amount of 0.5 to 15% by weight and having a limiting viscosity of 0.3 to 10 dl/g, and 1 to 300 parts by weight of glass fibers based on 100 parts by weight of the sum of the 4-methyl-1-pentene polymer and the graft-modified polymer. The composition has overall standards of mechanical strength, heat resistance and water resistance.
