The present invention relates to a polyvinyl chloride (PVC)-based compound composition, and more specifically, to a PVC-based compound composition that uses a PVC-based copolymer having internal plasticity prepared by suspension polymerization together with a PVC resin, thereby increasing compatibility with the PVC resin to shorten the gelling time, lowering the load at the time of extrusion to increase production in the same process conditions, and partially showing an impact modifier substitution effect.
本发明涉及一种聚氯乙烯(PVC)基化合物组合物,更具体地说,涉及一种聚氯乙烯基化合物组合物,该组合物使用通过悬浮聚合制备的具有内部可塑性的聚氯乙烯基共聚物和聚氯乙烯树脂,从而提高了与聚氯乙烯树脂的相容性,缩短了胶凝时间,降低了挤出时的负荷,提高了相同工艺条件下的产量,并部分显示了抗冲改性剂的替代效果。
