Copolyimides from aliphatic and aromatic anhydrides and diamines |
| 摘要 |
Novel copolyimides are prepared from mixtures of tetramethyl-cyclobutane-1,2,3,4-tetracarboxylic dianhydride and other aliphatic and aromatic dianhydrides. Their dianhydride mixtures are reacted with aliphatic or aromatic diamines to form copolyimides which are useful as engineering plastics.
