ABSTRACT

In this paper, 80/20 polyamide 6 (PA6) and acrylonitrile–butadiene–styrene (ABS) blends and 80/20 PA6/ABS blend with various compatibilisers, such as styrene-acrylic acid (SAA) and styrene-maleic anhydride (SMA-8 and SMA-14) have been investigated. The objectives were to understand the effect of reactive compatibilisation on morphology, crystallinity, thermal stability and mechanical properties. It was found that compatibiliser helps to refine the morphology. It further helps decrease the interparticle ligament thickness and increase interfacial area per unit volume of the dispersed phase (ABS) in the PA6 matrix. Furthermore, crystallisation, thermal stability and storage modulus were improved for blends with various compatibilisers compared to the neat combinations. The correlation of storage modulus with morphology, crystallinity and thermal stability reveals that SMA was a better compatibiliser for improving morphology, mechanical and thermal properties than SAA.

摘要

在本文中，80/20 聚酰胺 6 (PA6) 和丙烯腈-丁二烯-苯乙烯 (ABS) 共混物以及 80/20 PA6/ABS 与各种相容剂共混，例如苯乙烯-丙烯酸 (SAA) 和苯乙烯-马来酸酐 (SMA) -8 和 SMA-14) 进行了调查。目的是了解反应增容对形态、结晶度、热稳定性和机械性能的影响。发现增容剂有助于细化形态。它进一步有助于降低颗粒间韧带厚度并增加 PA6 基质中每单位体积分散相 (ABS) 的界面面积。此外，与纯组合相比，具有各种相容剂的混合物的结晶度、热稳定性和储能模量得到改善。储能模量与形态的相关性，
