Abstract

本发明涉及以丙交酯与δ-癸内酯为单体，醇为引发剂，1，5，7-三氮杂二环[4.4.0]癸-5-烯为催化剂，二氯甲烷为溶剂制备聚乳酸-聚δ-癸内酯的嵌段共聚物。

Description

一种聚酯嵌段共聚物
技术领域
本发明涉及以丙交酯与δ-癸内酯为单体共聚制备聚丙交酯-聚δ-癸内酯嵌段共聚物。
背景技术
近年来，基于聚乳酸(也称聚丙交酯)的可再生高分子材料在生物医药、包装等领域得到了广泛的研究和应用。然而，聚乳酸材料本省硬、脆、玻璃化转变温度高、断裂伸长率低等性质限制了其更为广泛的应用。通过与其他脂肪族聚酯共聚是有效改善上述性能的有效方法，如Ann-Christine Albertsson及Jun Ling等分别报道了以ε-癸内酯与丙交酯开环共聚合得到嵌段共聚物，共聚物较聚乳酸在断裂伸长率方面有了显著的提高。然而，目前关于丙交酯与δ-癸内酯共聚物的却未见相关专利。
发明内容
为实现本发明所提供的技术方案是：
以丙交酯与δ-癸内酯为单体，醇为引发剂，1，5，7-三氮杂二环[4.4.0]癸-5-烯为催化剂，二氯甲烷为溶剂制备聚丙交酯-聚δ-癸内酯的嵌段共聚物。
具体实施方式
为更好理解本发明，下面结合实施例对本发明做进一步地详细说明，但是本发明要求保护的范围并不局限于实施例表示的范围。
实施例1：
将10mg对苯二甲醇溶解于1gδ-癸内酯，然后加入20mg催化剂1，5，7-三氮杂二环[4.4.0]癸-5-烯，室温下反应24小时，然后加入4mL二氯甲烷稀释聚合体系。将1g丙交酯溶于8mL二氯甲烷中，加入到癸内酯的聚合体系中，继续反应30分钟，然后加入100mg苯甲酸终止聚合。将聚合物溶液滴加至100mL甲醇中，抽滤，所得固体干燥后为1.6g。得聚丙交酯-聚δ-癸内酯-聚丙交酯三嵌段共聚物。
实施例2：
将5mg对苯甲醇溶解于1gδ-癸内酯，然后加入20mg催化剂1，5，7-三氮杂二环[4.4.0]癸-5-烯，室温下反应24小时，然后加入4mL二氯甲烷稀释聚合体系。将1g丙交酯溶于8mL二氯甲烷中，加入到癸内酯的聚合体系中，继续反应30分钟，然后加入100mg苯甲酸终止聚合。将聚合物溶液滴加至100mL甲醇中，抽滤，所得固体干燥后为1.6g。得聚丙交酯-聚δ-癸内酯双嵌段共聚物。
