Polymer concrete possesses viscoelastic properties conditioned by relaxation processes in the polymer binder. Their acceleration with an increase of temperature (principle of time-temperature equivalence) is used in predicting the long-term creep of polymer concrete. Physical aging of the polymer bi

Abstract
The longβterm creep of polymer concrete was predicted with the structural approach and with the phenomenological model of the creep of a polymer binder (polyester resin). The physical aging of polyester resin during the previous exposure of the composite at elevated temperatures and its subsequent creep was examined. The model accounted for the deceleration of relaxation processes in the polyester resin and its shrinkage. Β© 2003 Wiley Periodicals, Inc. J Appl Polym Sci 89: 3427β3431, 2003

Changes in mechanical properties during isothermal physical aging were investigated for three miscible blends: polystyrene ( PS ) / poly ( 2,6-dimethyl 1,4-phenylene oxide ) ( PPO ) , PS / poly ( vinylmethylether ) ( PVME ) , and poly ( methylmethacrylate ) ( PMMA ) / poly ( ethyleneoxide ) ( PEO )
Volume recovery measurements have been used to study the physical aging behavior of a polyetherimide. Isothermal aging temperatures near T g were studied with aging times ranging up to several days. The volume decreases during physical aging and levels off at equilibrium. For comparison purposes, th
