Rheological properties and molecular structure of polymer melts

摘要: An overview is given on relations between some features of the molecular structure polymers and their viscous elastic properties in molten state. Moreover, it discussed how elongational behaviour polymer melts can be affected by parameters. Besides effects molar mass distribution, more recent results influence long-chain branching rheological are presented. While rheology processing addressed only shortly, applications investigations with respect to a characterisation detection small amounts branches, particular, detail. Although obtained materials rather simple structure, described this short review have potential used for other polymeric field soft matter, too.
