摘要:
Polymers comprising carbonyl groups in their backbone, such as polyesters and polyimides, which have been modified by compounds having ketonic groups in their backbone, and molecular weights in the region of 300 to under 1,000. Preferably, these compounds have also ether groups in their backbone.
