| Outline of Final Research Achievements |
The purpose of this work is to clarify the role of entanglement species on the crystallization of polymers through observation of crystallization of a topological blend polymer which consists of cyclic polymer. Topological blend polymer means the mixing of cyclic and linear polymers. The following issues were investigated. (1) Several kinds of cyclic and linear polyethylene with different molecular weight were prepared. Crystallization at the quiescent state and under the flow were observed by means of polarizing optical microscope. The degree of supercooling, flow rate and strain dependence of the crystallization behavior were made clear. (2) Observation by a scanning electron microscope and crystal structure analysis by wide angle X-ray diffraction measurement were performed for various blends samples.
