VINYL CHLORIDE POLYMER COMPOSITION, MANUFACTURING METHOD THEREOF, AND MOLDING FORMED THEREFROM

Japanese Patent JP3802818

B2

PROBLEM TO BE SOLVED: To provide a vinyl chloride polymer composition which gives excellent toughness in such breakdown mode as crack propagation at a long-term use, while maintaining high elastic modulus characteristic of a vinyl chloride polymer and without damaging tensile elongation characteristics, to provide its manufacturing method, and to provide a molding obtained from the composition.
SOLUTION: In the composition, (A) the vinyl chloride polymer has an average degree of polymerization of 600 or more, (B) a stratified swelling silicate is the one in which part of exchangeable inorganic cations present between the layers is substituted by organic cations, (C) the stratified swelling silicate dispersed in the composition has an average layer thickness of 0.5-50 nm and an average aspect ratio (ratio of layer length and layer thickness) of 10 or more, and (D) the stratified swelling silicate leaves 0.05-0.7 wt.% of the composition as the residue when the composition is completely burned at 950°C.
