The present invention provides a PVC resin including a vegetable oil-derived environmentally-friendly processability improver of chemical formula 1. In the chemical formula 1, the n and m are independently integers of 2 to 10, and R1 is C1-C6 alkyl. Accordingly, according to the present invention, a vegetable oil-derived environmentally-friendly processability improver and a PVC inducer are dissolved and processed, so production costs are remarkably reduced. Also, by decreasing a dissolving and processing temperature, chlorine smells generated during a dissolving step can be effectively removed. The PVC resin including a vegetable oil-derived environmentally-friendly processability improver can be easily produced into a molded product at a low temperature. At the same time, the PVC resin including a vegetable oil-derived environmentally-friendly processability improver have remarkably improved physical properties compared to a conventional PVC product. Moreover, the vegetable oil-derived environmentally-friendly processability improver of the present invention can be used not only for a PVC resin but also for a bioplastic material such as PLA. |
