Abstract: The aliphatic polyester expressed by a general formula (I), is new. - The aliphatic polyester is expressed by a general formula (I): (-CO-[R1]t-CO-O-R2-O-)p (I) t = molar fraction of ester portion within range of 0 or 1; r is molar fraction of ester portion which is in the range of 0.001-0.10; The R1 =(CH2)2; and R2 = (CH2)4. An independent claim is also included for aliphatic polyester manufacturing method.

Abstract: An aliphatic copolyester having a plurality of first ester units of the formula : - CO - [R 1 ] t - CO - O - R 2 - O - wherein R 1 represents a divalent aliphatic group, R 2 represents a divalent aliphatic and t is an integer of 0 or 1, and a plurality of second ester units of the formula: wherein R 1 and t are as defined above and R 3 represents an aliphatic group. The molar ratio of the first ester unit to the second ester unit is 90:10 to 99.9:0.1. The copolyester is produced by reacting an aliphatic diester e.g. dimethyl succinate with an aliphatic glycol e.g. 1,4 butanediol and with a monoacylated glycerin and with a monoacylated glycerin e.g. glyceryl a -monolaurate under ester exchanging conditions.
