ESTER-BASED PLASTICIZER

摘要

The present invention relates to a novel ester-based plasticizer, and more specifically to one which is produced by means of an esterification reaction between a polyhydric alcohol, alkylene oxide and a fatty-acid or aromatic carboxylic acid. When the plasticizer according to the present invention is used to produce a poly(vinyl chloride) resin, there are advantageous effects in that it is possible to obtain products with outstanding plasticization efficiency, and physical properties such as hardness and tensile strength are also improved.
