摘要: Biobased dihydroxy-terminated aliphatic copolyesters were synthesized from melt-polycondensation of 1, 6-adipic acid with 1, 6-hexanediol and 1, 10-decanediol. The isodimorphic behavior of the copolyesters was explored to identify the pseudo-eutectic copolyester, which was selected as macro-initiator for ring opening polymerization of l-lactide to prepare poly (l-lactide)-b-poly (hexamethylene-co-decamethylene adipate)-b-poly (l-lactide)(PLLA-b-PHDA-b-PLLA) triblock copolymers varying PLLA block length. The …
