摘要
作为一种长碳链聚酰胺,PA1012具有较长的相邻亚甲基链段和相对较低的酰胺键及氢键的密度,因而在宏观性能上表现出韧性好、结晶度低、熔点低等特点。国外起步较早,阿克玛、德国赢创公司等是国外的主要生产企业,而国内生产厂商不多,且关于原料、聚合改性的方面所披露的研究较少。本文综述了国内外利用共混和共聚改性PA1012的相关研究,分析了共混成分、配比对改性PA1012的力学、结晶等性能的影响。最后,针对此领域亟待解决的问题进行了总结,并对未来的发展提出了一些思路和建议。
As a long carbon chain polyamide,PA1012 has long adjacent methylene chain segments and relatively low density of amide bond and hydrogen bond,so it has the characteristics of good toughness,low crystallinity and low melting point.Akma and Evonik are major foreign manufacturers,while there are few domestic manufacturers,as well as few studies on raw materials and polymerization modification.In this paper,the related studies on the modification of PA1012 by blending and copolymerization at home and abroad are reviewed,and the effects of blending composition and ratio on the mechanical and crystallization properties of modified PA1012 are analyzed.Finally,the problems to be solved in this field have been summarized,and some ideas and suggestions for future development have been put forward.
