COMPRESSION CREEP OF ABS POLYMERS

Compression creep measurements on acrylonitrile-butadiene-styrene (ABS ) polymers were conducted to compare with the results of the impressio n creep tests at similar stress levels and testing temperatures. The c reep curves of ABS polymers obtained from the compression tests were s imilar to those from the impression tests, namely they ail exhibited t ransient and steady-state stages. The stress and temperature dependenc es of the steady-state strain rate obtained from the compression tests were in general agreement with the corresponding quantities obtained from the impression tests at temperatures below 353 K; however, they d eviated from each other at higher temperatures.
