与脂肪族聚酰胺相比,PPA具有更好的[7][8][9][10]
PPA的玻璃化温度随着TPA用量的增加而升高。[6]如果PPA 55%以上的酸性部分是由IPA构成的,那么共聚物就是无定型的。[6]简言之,结晶度有助于提高物质在玻璃化转变温度以上(但低于熔点)的耐化学性和机械性能。无定型聚合物具有良好的低翘曲性和透明度。
像脂肪族尼龙一样,PPA可以(事实上几乎总是)用如玻璃纤维、增韧剂和/或稳定剂等增强剂来改性。
目前已开发出多种具有特定性质的配方。例如能够直接粘合到弹性体上,形成塑料-橡胶复合材料的树脂,以及经批准可以与饮用水和食物直接接触的树脂。[11]
向PPA (PPA/PA共混物)中添加脂肪族聚酰胺能够降低熔点和玻璃化温度,这可能使这些聚邻苯二甲酰胺共混物比具有较高熔点/软化点的PPA更容易加工。
虽然对聚酰胺/聚烯烃共混物进行了大量的研究,但关于PPA/聚烯烃共混物的性能却鲜有报道。这可能是因为与聚烯烃的温度稳定性相比,PPA树脂需要相对较高的加工温度。PPA/聚酰胺/聚烯烃共混物显示出延展性、强度、刚度、抗冲击性和热性能的良好平衡,表明这些类型的材料应该具有商业用途。[12]
与任何热塑性塑料一样,PPAs理论上可以通过重熔完全回收,通过解聚作为缩聚物回收。商业回收要求物流、清洁和加工成本低于原始聚合物的成本,但情况并非总是如此。能够产生能量的PPA废物可以在焚烧厂回收。最佳回收选项取决于许多条件,如当地立法、塑料零件设计、使用分拣设施以及回收成本。
