共聚酯醚弹性体英文名称为Copolyester-ether Elastomers,缩写为COPEs。COPEs是一类通过共聚形成的高弹性模量的弹性体,由醚键将硬段和软段相连。硬段通常为结晶态的PBT或PET;软段为非晶态的聚对苯二甲酸四亚甲基醚乙二醇酯,可由对
Copolyester ether elastomer English name is Copolyester-ether Elastomers, abbreviated as COPEs. COPEs are a class of elastomers with a high modulus of elasticity formed by copolymerization. The hard and soft segments are connected by ether linkages. Hard segment is usually crystalline PBT or PET; Soft segment is amorphous poly (tetramethylene ether glycol ester), by
