Abstract

The polyester-based plasticizer of the present invention is obtained by reacting (a) a diol component, (b) an organic dicarboxylic acid component, and (c) a terminal terminator, and the average molecular weight of the polyester-based plasticizer is 500-5000, wherein, the (a) diol component is composed of 100 mole parts of 2-methyl-1,3-propanediol, 10-1000 mole parts of 3-methyl-1,5-pentanediol and 0-1000 mole parts of other aliphatic diols; the (b) organic dicarboxylic acid component is composed of 100 mole parts of adipic acid and 0 to 100 mole parts of other organic dicarboxylic acids; the (c) terminal The terminator is composed of monohydric aliphatic alcohol or monohydric aliphatic organic acid. The polyester plasticizer of the present invention has excellent plasticizing efficiency and can impart excellent oil resistance to synthetic resins such as chlorine-containing resins.

Description

technical field [0001] The present invention relates to a specific polyester-based plasticizer and a chlorine-containing resin composition containing the plasticizer. -Polyester-based plasticizer obtained by reacting diol component with pentanediol as an essential component, organic dicarboxylic acid component with adipic acid as an essential component, and terminal terminator, and chlorine-containing resin containing the plasticizer combination. Background technique [0002] Polyester compounds obtained from aliphatic diols and aliphatic dicarboxylic acids are useful as plasticizers for synthetic resins, and are widely used as plasticizers for chlorine-containing resins such as vinyl chloride resins. [0003] JP-A-61-78827 discloses a polyester-based plasticizer having improved low-temperature flexibility obtained by using 2-methyl-1,3-propanediol as an aliphatic diol. However, this polyester-based plasticizer has low plasticizing efficiency and cannot impart sufficient o...
