Copolymides with a combination of flexibilizing groups. |
摘要 |
Novel copolyimides are prepared by reacting one or more aromatic dianhydrides with a meta-substituted phenylene diamine and an aromatic bridged diamine. The incorporation of meta-substituted phenylene diamine derived units and bridged aromatic diamine derived units into the linear aromatic polymer backbone results in a copolyimide of improved flexibility, processability, and metal-flow characteristics. The novel copolyimides are especially useful as thermoplastic hot-melt adhesives.
