Abstract
|
This paper describes the 70/30 wt% composition of SAN/PA6 blends having different types of morphology, namely PA6 dispersed in SAN, a co-continuous structures of PA6 and SAN, and a <IMGSRC="/giflibrary/12/ldquo.gif"BORDER="0">mixed structure<IMGSRC="/giflibrary/12/rdquo.gif"BORDER="0"> which exhibits PA6 particles in SAN which themselves form the matrix for smaller SAN particles. These morphologies were achieved by using different processing conditions during extrusion blending in a twin screw extruder, especially variation in the screw speed and by injection molding. Morphological analysis using SEM and TEM, solubility experiments, DMA, and oscillatory rheometry are presented. These methods were shown to be able to distinguish between the different types of morphology. In addition, DSC was used to detect the PA6 crystallization behavior.
