Abstract

Abstract: The rheological properties of acrylonitile-styrene-acrylate copolymer(ASA) have been studied by means of rheometer. The effect of shear rate, shear stress, and temperature on the viscosity of ASA was discussed. It showed that the apparent viscosity decreased and the non-Newton index increased with increasing temperature. The visco-flow activition energy decreased with the increasing of shear rate. The non-Newton index was less 1, indicating a typical pseudo-plastic nature of the melt of ASA copolymer.

Key words: ASA copolymer, capillary, rheological property, apparent viscosity
