PURPOSE: The titled composition having improved heat resistance, molding and processing properties without damaging improved mechanical and electrical properties of resin, obtained by adding a specific polypropylene resin to a specific aromatic polyester resin.
CONSTITUTION: 100pts.wt. aromatic polyester comprising structure units shown by the formula I , formula II, and formula III (CO is in meta- or para-position; O is in meta- or para-position based on SO2; X is 1W10C bifunctional hydrocarbon group, O, SO2, etc.; a is 0 or 1; R1W4 are H, or 1W8C hydrocarbon group, or halogen; when X is SO2 and a is 1, R1W4 are not H at the same time), having N2/N1=0.04W1.06, N3/N1=0.04W1.06, and (N2+N3/N1)=0.99W1.10 when numbers of existence of the structural units shown by the formula I , formula II, and formula III are N1, N2, and N3, respectively, showing 0.4W2.0 logarithmic viscosity, is blended with 3W30pts.wt., preferably 10W20pts.wt. polypropylene resin having ≤2g/10min melt flow ratio, and the blend is pelletized.
