Gloss reduction and morphological properties of polycarbonate and poly(methyl methacrylate-acrylonitrile-butadiene-styrene) blends with SAN-co-GMA as a reactive compatibilizer

Abstract

The gloss properties of the polycarbonate (PC)/poly(methyl methacrylate-acrylonitrile-butadiene-styrene) (MABS) blend with styrene-acrylonitrile-co-glycidyl methacrylate (SAN-co-GMA) as a compatibilizing agent were investigated. For the PC/poly(MABS)/SAN-co-GMA (65/15/20, wt %) blend surface, the reduction of gloss level was observed most significantly when the GMA content was 0.1 wt %, compared with the blends with 0.05 wt % GMA or without GMA content. The gloss level of the PC/poly(MABS)/SAN-co-GMA (0.1 wt % GMA) blend surface was observed to be 35, which showed 65% lower than the PC/poly(MABS)/SAN-co-GMA blend without GMA content. The gloss reduction was most probably caused by the insoluble fractions of the PC/poly(MABS)/SAN-co-GMA blend that were formed by the reaction between the carboxylic acid group in poly(MABS) and epoxy group in SAN-co-GMA. The results of optical and transmission electron microscope analysis, spectroscopy study, and rheological properties supported the formation of insoluble structure of the PC/poly(MABS)/SAN-co-GMA blend when the GMA content was 0.1 wt %.
