| Outline of Final Research Achievements |
Polymers with hydroxyl group in their side chain have been widely used for food-packaging films and electronic coatings, because of their good gas-barrier properties. In this research, synthesis and properties of a new poly(hydroxyl ether) with amide and imide structure in main chain is studied. The poly(hydroxyl ethers) exhibited good thermal and gas-barrier properties. Further, novel polymer alloy consisted of the poly(hydroxyl ethers) and thermoplastic polyimide was prepared. Relationship between the composition of polymer alloys and the properties were studied. The glass transition temperature of polymer alloys was lowered with increasing the poly(hydroxyl ether) content. On the other hand, moisture barrier property of polymer alloy was improved compared with thermoplastic polyimide, probably due to an interaction between the both polymers. Additionally, compatibility of the polymer alloy was presumed to be semi-compatible property from results of dynamic mechanical analysis.
