摘要： PURPOSE: To obtain a polyester-based plasticizer by using nonanediol as a dihydric alcohol having excellent freeze resistance, low bleeding, showing excellent plasticizing efficiency and low-temperature flexibility when blended with a vinyl chloride-based resin. CONSTITUTION: This plasticizer is a polyester comprising an ester of a dibasic acid component (preferably adipic acid) and a dihydric alcohol component in which the dihydric alcohol residue is 1,9-nonanediol residue. The ratio of 1,9- nonanediol residue in the dihydric alcohol residue is preferably >=50mol%. A 3-12C dihydric alcohol component such as 1,2-propanediol is preferably used as the dihydric alcohol component except 1,9-nonanediol. A plasticizer having 1,500-7,000 molecular weight has excellent balance of freeze resistance and bleeding properties and is practically preferable as the plasticizer.
