Abstract
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.
