Mechanical properties of solid polymers
TL;DR: A concise, self-contained introduction to solid polymers, the mechanics of their behavior and molecular and structural interpretations can be found in this article, which provides extended coverage of recent developments in rubber elasticity, relaxation transitions, non-linear viscoelastic behavior, anisotropic mechanical behavior, yield behavior of polymers and other fields.

Molecular motions in polyethylene terephthalate
K.H. Illers,H. Breuer +1 more
TL;DR: In this paper, the molecular motions in polyethylene terephthalate samples of different crystallinities have been investigated by dynamic mechanical measurements at a frequency of 1 cycle/sec. between −180° and +260°C.

Glass transition temperature of copolyesters of PET, PEN and PHB as determined by dynamic mechanical analysis
D. Chen,Hans Gerhard Zachmann +1 more
TL;DR: In this paper, a linear dependence of the glass transition temperature of the isotropic materials on composition was obtained, and the PET/PEN/PHB ternary copolyester containing equal parts of each of the three components can be obtained at room temperature as a liquid-crystalline glass and as an isotropically glass, depending on thermal history.

Molecular Structure Effects on the Secondary Relaxation and Impact Strength of a Series of Polyester Copolymer Glasses
TL;DR: The secondary relaxations of a series of glassy copolymers based on poly(ethylene terephthalate) (PET) and poly(1,4-cyclohexylenedimethylene Terephthalates) (PCT) involve cooperative motions of the...
