Abstract
The present invention relates to a novel ester-based plasticizer, and, more particularly, to an ester plasticizer, which is synthesized by esterifying a polyhydric alcohol and an alkylene oxide with an aliphatic carboxylic acid or an aromatic carboxylic acid. When a polyvinylchloride resin is manufactured using the ester-based plasticizer, there are advantages in that products having a high plasticizing efficiency can be obtained and in that products having excellent physical properties, such as hardness, tensile strength, etc., can be obtained.
