Relationship between the interfacial tension and compatibility of polycarbonate and poly(acrylonitrile–butadiene–styrene) blends with reactive compatibilizers

Abstract

We studied the morphological, mechanical, and rheological properties of polycarbonate (PC) and poly(acrylonitrile-butadiene-styrene) (PolyABS) blends with different types of compatibilizer. Styrene-acrylonitrile-maleic anhydride terpolymer (SAM) was used as a compatibilizer of the blends. For comparison, styrene-acrylonitrile-glycidyl methacrylate terpolymer (SAG) was also used as a compatibilizer. For the PC-PolyABS (70/30 wt %) blends with SAM, the mechanical strength and complex viscosity reached a maximum when the SAM concentration was 5 phr. The mechanical and rheological results of the blend were consistent with the morphological result that the PolyABS domain size reached a minimum when the SAM content was 5 phr. The interfacial tension (a) of the blend was compared with the compatibilizer type and content, which were calculated by the Palierne emulsion model with the relaxation time of the PC-PolyABS blend. The a is consistent with the morphological and mechanical properties of the PC-PolyABS blend. The results of the morphological, mechanical, and rheological properties of the blend suggest that SAM was a more effective compatibilizer than SAG, and the optimum compatibilizer content of SAM was 5 phr.

Weathering properties and hydrolysis of poly(butylene terephthalate)/poly(acrylonitrile‐co‐styrene‐co‐acrylate) blend with reactive compatibilizer

“…Figure shows the size distribution of PBT/PolyASA blend with the addition of EGMA‐ g ‐SAN content. Figure was obtained from the analysis of variance technique, which is one of the widely used methods for data analysis . It is evident in Figure that the PBT/PolyASA blend with EGMA‐ g ‐SAN (3 phr) has the smallest domain size and narrowest size distribution.…”

“…The morphology of the PBT/PolyASA (70/30) blend was measured by transmission electron microscopy (TEM; model: JEM‐1400, JEOL Co., Tokyo, Japan), operating at an accelerating voltage of 120 kV with a magnification of 6000. The blend samples were microtomed with a diamond knife and were stained with osmium tetroxide and ruthenium tetroxide (4:1) for 16 h. To analyze the size of the dispersed phase, 20 domains were counted from the TEM picture, and the average domain size was measured using an image analysis program (Image J software) …”
