脂肪族二醇類對改質聚酯熱性質的影響

The study of Modified Polyester Thermal Properties Based on Aliplatic Diols

摘要


本文主要探討聚酯纖維在聚合反應工程中添加不同比例之脂肪族二醇類改質單體,觀察聚酯共聚合物物性變化的情形。結果顯示,隨著二種改質單體添加的莫耳數比例越高,則呈現Tg及Tm點有越低現象,而熱結晶溫度則有隨著添加比例增加而提高的現象。

並列摘要


The research mainly focuses on polyethylene terephthalate copolymer character behavior for added aliplatic diols upgrading monomer in melt polymerization. The result showed that the more ratio of upgrading monomer is increased, Tg or Tm could be decreased. However the heat-crystallization temperature could be increased.
