利用碳酸乙烯酯开环产物合成聚氨酯脲弹性体
Synthesis of Poly(urethane-urea)s Elastomers by Using Ring-opening Products of Ethylene Carbonate
摘要
Abstract
The comprehensive utilization of carbon dioxide is the major issue related to human and environment.In this paper,aliphatic urethane diols was firstly synthesized from ethylene carbonate,which is the derivative of carbon dioxide,and 1.6-diaminohexane.Then aliphatic polycarbonate poly(urethane-urea)s elastomers were synthesized from aliphatic polycarbonate diols (PCDL),isophoronodiisocyanate (IPDI),and the ring-oping product which was used as a chain extender.The results show that ring-opening product,1,6-bis(2-hydroxy-ethoxy carbonylaminohexane(DHDU),was obtained after reaction for 10 h at 38℃,with a yield of 89.9 wt％,and the mechanical propertie of poly(urethane-urea)s elastomers could be adjusted by changing the ratio of hard segments,which were the urethane and urea units formed by ring-oping product with IPDI,in polymer chains.As the molar ratio of PCDL to DHDU decreased,the tensile strength and hardness of elastomers increased and the elongation at break of elastomers decreased when the molecular weight of PCDL kept unchanged.The synthetic elastomer would have broad application prospects in the field of biological materials.关键词
