合成了一种由聚二羧酸亚烯和聚1,4-环己二羧酸丁烯衍生的新型无规脂肪族共聚酯，并对其分子结构和热性能进行了表征。特别地，讨论了摩尔组成、脂肪序列长度和1,4-环己烯单元的顺反比对结晶和非晶相特性的影响。已经发现了一些有趣的结构-性质关系。这些材料具有潜在的生物可降解性和良好的物理性能，并且可以根据特定应用的要求，通过微小的分子结构变化很容易地进行修饰，因此是非常有前途的新型生物聚合物。
Novel aliphatic, random copolyesters, containing co-units derived from a poly(alkylene dicarboxylate) and a poly(butylene 1,4-cyclohexanedicarboxylate), have been synthesized and characterized in terms of molecular structure and thermal properties. In particular, the effects of the molar composition, the length of the aliphatic sequences, and the cis/trans ratio of the 1,4-cyclohexylene units on the characteristics of the crystalline and amorphous phases are discussed. Some interesting structure-property relationships have been found. The materials result to be very promising new biopolymers as they are characterized by a potential biodegradability and good physical properties, which can be easily modified, according to the requests of specific applications, by little changes in the molecular structure.
