- Abstract
- Kinetics of uniaxial mechanical tensile deformation of following types of polymers: linear chains in diluted solution, thermoplastic polymers and thermoset (tree-dimensional) polymers at constant temperature was considered. It was shown that at stretching strain linear chains were expanded (were straighten up) with decreasing or even loss of torsional as oscillations and/or changing of conformational composition. After straightening of polymers with local intermolecular interaction between chains (cross-linked and linear) this interaction was destroyed. After loss of local inter molecular interaction deformation of separate parts of chains was observed. Local intermolecular interaction applears anew after finishing of stretching of chains separate parts. At continuation of deformation sample was destroyed.
