Abstract
A synthetic resin composition having heat deterioration resistance comprising: (A) 100 parts by weight of a synthetic resin; and (B) 0.001 to 10 parts by weight of hydrotalcite particles defined by the following (i) to (iv): (i) the hydrotalcite particles are represented by the following chemical structure formula (1): {(Mg).sub.y (Zn).sub.z }.sub.1-x (Al).sub.x (OH).sub.2 (A.sup.n-).sub.x/n.mH.sub.2 O (1); (ii) the hydrotalcite particles have an average secondary particle diameter of 2 .mu.m or less; (iii) the hydrotalcite particles have a specific surface area (measured by a BET method) of 1 to 30 m.sup.2 /g; and (iv) the hydrotalcite particles contain an iron compound and a manganese compound in a total amount of 0.02 wt % or less in terms of metals (Fe+Mn). A molded article formed from the above resin composition of the present invention is excellent in heat deterioration resistance and impact resistance and satisfactory in the dispersibility of hydrotalcite particles.
