摘 要: | 以精对苯二甲酸(PTA)和1,4-丁二醇(BDO)为基本原料,在5 L熔融缩聚反应釜中,采用原位聚合工艺,通过加入自制纳米氧化锌(nano-ZnO),制备得到聚对苯二甲酸丁二醇酯(PBT)/nano-ZnO复合材料。采用差示扫描量热仪对PBT/nano-ZnO复合材料的结晶性能进行测试,并研究了复合材料的非等温结晶行为。结果表明,加入nano-ZnO后,不影响PBT的聚合工艺,nano-ZnO对PBT有异相成核作用;Jeziorny法可以很好地分析PBT及其复合材料的非等温结晶过程。

Preparation and Crystallization Behavior of PBT/nano-ZnO Composites Through In Situ Polymerzation |
| |
Abstract: | Terephthalic(PTA) and butanediol (BDO) were condensed in a 5 L reactor and nano ZnO was introduced into the system leading to poly(butylene terephthalate)/ZnO nanocomposites. The non-isothermal crystallization behavior of the nanocomposites was investigated using differential scanning calorimetry (DSC). It showed that the nano ZnO could act as a nucleation agent for PBT. The Jeziorny method could be applied to analyze the non isothermal crystallization process. |

Keywords: | poly(butylene terephthalate) in-situ polymerization nano-zinc oxide nonisothermal crystallization |
