| Outline of Final Research Achievements |
Novel polymers were designed and synthesized to obtain poly(diphenylacetylene)s having polar groups. Polymerization conditions were examined in detail, and we established the polymerization method to obtain high-molecular-weight polymer in high yield. We also established the method to obtain polar group-containing polymer membranes which cannot be obtained by the previous method. Poly(diphenylacetylene)s having polar groups such as imidazolium salts, sulfonic acid, and amino groups exhibited relatively high CO2 permselectivity due to the high affinity to CO2 molecule. The cross-linked membranes of poly(vinyl ether) possessing oxyethylene chains showed pretty high CO2 permeability and selectivity because of the flexibility of polymer chain and high affinity to CO2 molecule.
