Rheological properties of mixtures of amorphous and crystalline polymers using a mixture of polyamide with an acrylonitrile-styrene copolymer

Abstract

Rheological properties of acrylonitrile-styrene copolymer and P-6 polyamide mixtures were examined in the entire range of composition at different temperatures. It was shown that on adding to this copolymer small amounts of P-6 solid particles, viscosity is subject to irregular reduction while the maximum Newtonian viscosity of the system is noticeably reduced. Experiment proves that molecular interaction is intensified on the phase interface of the two component polymer mixture. None of the well known theoretical relations gives a description of the experimental course of the curve showing viscosity vs. composition in the entire range of concentration.
