| 摘 要： | 由聚对苯二甲酸乙二酯(PET)和对-乙酰氧基苯甲酸制得的PET/PHB共聚酯代表了一类序列结构较一般二元共聚物复杂的共聚体系.在揭示了这类共聚物与序列分布有关的诸概率参数中只有一个是独立的之后,定义了参数B_q来描述此类共聚物的无规度.并指出,共聚物B_q=b时的序列分布,可以从一般二元共聚物无规度B=b时的序列结构加以推断.

| Abstract: | PET/PHB copolyesters made from poly(ethylene terephthalate) (PET) and p-acetoxyben-zoic acid represent a kind of copolymers whose sequence structure is more complicated compared with the general binary copolymers. Based on the statistical analysis on sequence distribution of the copolyesters, a parameter, Bq, has been proposed to describe the degree of randomness of the copolyesters. It has been shown that the sequence distribution of the copolymer with Bq = b can be evaluated by comparing with the sequence structure of the general copolymer whose degree of randomness, B equals b. |
