Outline of Final Research Achievements |
The mechanical properties became brittle and a filament-shaped porous structure with periodic distance was found to be obtained by stretching low molecular weight polycarbonate under CO2. Distorted domain crystals with uniform optical anisotropy were found to be obtained under CO2 at wide temperature regions by melt crystallization of thermoplastic polyurethanes, while spherulites with Maltese-cross pattern could be obtained at limited temperature region under air at ambient pressure. The difference of the crystalline morphology might be attributed to the change of the microphase separated structure under CO2.
