PURPOSE: To obtain a synthetic resin composition excellent in heat resistance, colorability, weatherability, processing stability, and antistatic properties.
CONSTITUTION: This composition is obtained by blending 100 pts.wt. synthetic resin with 0.001-5 pts.wt. organic phosphonite compound represented by formula I (wherein R1 is tert-butyl or tert-amyl; R2 is 1-8C alkyl, and R3 is H or 1-8C alkyl), 0.001-5 pts.wt. alkanolamine represented by formula II (wherein R4 is 8-30C alkyl, alkenyl, alkenoyl or alkanoyl; R5 is 2-4C alkylene; n and m are each 1 to 4; and X is H or 2-30C alkanoyl or alkenoyl) and 0.001-5 pts.wt. of at least one aluminum compound selected among basic inorganic aluminum compounds and aluminum salts of 8-30C aliphatic carboxylic acids.
