Dynamic Viscoelastic Properties of ABS Polymers in the Molten State

Abstract

The dynamic viscoelastic properties of ABS resins were measured in the molten state with a rotating cylinder type rheometer over wide ranges of temperature and frequency. Two series of resins with rubber contents, 0, 10, 20, and 30 wt%, were prepared by blending an AS copolymer with two kinds of ABS resins having different ratios of grafted AS copolymer to butadiene rubber. The main results are summarized as follows. © 1979, The Society of Rheology, Japan. All rights reserved.
