Outline of Final Research Achievements

In this project we aimed at developing properties of polymers through studies of polymer crystallization via various intermediate structures, and their application to industry. We have studies three types of intermediate structures produced in spinodal-mechanism assisted polymer crystallization, flow-induced polymer crystallization and crystallization through stable intermediate structure in isotactic polypropylene and polyterephthalate. In addition to some new scientific findings, we found possibilities of industrial application of polymer crystals produced by laser-drawing and by flow application above nominal melting temperatures.
