摘要

己内酯与丙交酯的开环聚合及其共聚制备生物降解型聚酯是目前的研究热点。为降低聚合催化剂成本与毒性以便使聚合物可以用于食品包装等需求

我们采用三氯化铁在十四醇作用下实现了

-己内酯的开环聚合以及其与L-丙交酯的共聚。结果表明:三氯化铁可以高效引发己内酯开环聚合

通过调控聚合条件(如单体/铁比例、温度和时间)能够控制聚合活性与所得聚己内酯的分子量;也可以催化丙交酯开环聚合、以及己内酯与丙交酯的开环共聚。聚合方法以及共聚单体进料顺序显著影响共聚物结构。只有在先加入己内酯后加丙交酯的共聚反应中

才可以制备出嵌段共聚物PCL-

-PLA。此外

在氯化铁催化体系中原位引入等当量的两齿氮配体直接影响了己内酯开环聚合活性和所得聚合物分子量

从而实现不同分子量聚酯的可控制备。

Abstract

The ring opening (

-)polymerization of

-caprolactone or/and lactides produces the biodegradable polymers. Targeting the cost reduction and non-toxicity of its catalysts to meet the demanding for food packaging polymer

the ferric chloride with its initiator of 1-tetradecanol are currently explored in the ring opening (

-) polymerization of

-caprolactone or/and

-lactide. Results approve the good efficiency of FeCl

in ring opening polymerizing of

-caprolactone

and the polymerization parameters (such as molar ratio of monomer to iron

temperature and time) are useful in controlling the polymerization efficiency and resulting in polymers with different molecular weights. Extensively the catalytic system is also well active for the polymerization of

-lactide as well as copolymerization of

-caprolactone and

-lactide; the feeding order of monomers (

-caprolactone and

-lactide) and polymerization greatly influenced the microstructures of resultant polymers. The blocked copolymer

PCL-

-PLA can be only prepared with adding the first

-CL and then LA. In addition

the stoichiometric amount of compounds acting as N

N-bidentate ligands is added in FeCl

catalytic system

in situ

to influence the polymerization and adjust the molecular weight of polymers

in turn to realize the controllable polymerization.
