| Abstract: | A new chain entanglement viewpoint of polymer, that is the local inter-chain cohesion in the glassy state as a kind of cohesional chain entanglement, was used to explain the mechanism of the endothermic peak of aged polymers in DSC measurement and stress yielding in uniaxial stretching process. |

| Keywords: | chain entanglement physical ageing conformational relaxation stress yielding infrared spectroscopy |
