Abstract In the present work, a thorough description of creep response polymers in both linear and nonlinear viscoelastic domains is presented. According to proposed model, polymeric structure considered as an ensemble meso-regions linked with each other while they can cooperatively relax change their positions. Each meso-region has its own energy barrier that needs be overcome for transition occur. It was found distribution function, followed by barriers, attains decisive role, given it associated retardation times particular effect on materials’ time evolution. The crucial role imposed stress experiment influence spectrum extensively analyzed. model been successfully validated series data variety temperatures levels materials, studied experimentally elsewhere. Furthermore, model’s capability predict long-term analytically shown.
