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.
Claims10
A PVC-based compound composition comprising:
- a PVC resin;
- a stabilizer;
- and aPVC-based copolymer having internal plasticity,
- wherein the PVC-based copolymer having internal plasticity uses a vinyl chloride-based copolymer resin of a core shell structure alone or in a mixture, which has a vinyl chloride-alkyl acrylate polymer having an alkyl group with a carbon number of 1 to 20 in a core, has a polyvinyl chloride structure in a shell, and includes 10 to 50 wt % of an alkyl acrylate having an alkyl group with a carbon number of 1 to 20, based on the total weight of the copolymer resin.
