Compression creep measurements on acrylonitrile-butadiene-styrene (ABS) polymers were conducted to compare with the results of the impression creep tests at similar stress levels and testing temperatures. The creep curves of ABS polymers obtained from the compression tests were similar to those from the impression tests, namely they ail exhibited transient and steady-state stages. The stress and temperature dependences 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 deviated from each other at higher temperatures.
