Document Type and Number:
Japanese Patent JPH0948896
Kind Code:
A
Abstract:

To obtain the subject composition excellent in heat resistance and amine resistance, prevented in discoloration and deterioration and useful as a molding material for automotive interiors by adding a specific perchloric acid metal salt and hydrotalcite to vinyl chloride-based resin composition containing a plasticizer.

This composition is obtained by adding (C) barium perchlorate, sodium perchlorate or magnesium perchlorate, (D) tin perchlorate and (E) hydrotalcite free from water of crystallization to a resin composition obtained by carrying out dry blend of (A) a vinyl chloride-based resin with (B) a trimellitic acid ester based or a polyester-based plasticizer and further, as necessary, adding (F) a powder fluidity improver such as vinyl chloride-based resin having ≤10μm average particle diameter and obtained by emulsion polymerization or suspension polymerization thereto and preferably blending the component A with 0.5-10 pts.wt. component C, 0.01-5 pts.wt. component D, 0.5-10 pts.wt. component E and 5-30 pts.wt. component F based on 100 pts.wt. component A.
