PURPOSE:To obtain the subject composition capable of preventing flow scorch, excellent in flow properties, surface properties, gelation promoting effect and lubricating effect and useful for injection moldings of housing, etc., by adding a prescribed amount of specific processing acid to a PVC-based resin. CONSTITUTION:The objective composition is obtained by adding (B) 0.1-20 pts.wt. polyester (having 1000-100000 number-average molecular weight) obtained by condensation through dehydration from one or more kinds of dicarboxylic acids selected from aliphatic dicarboxylic acids, alicyclic dicarboxylic acids and aromatic dicarboxylic acids and an aliphatic polyol as a processing acid to 100 pts.wt. PVC-based resin. |
