ABSTRACT:
The present invention comprises reaction products resulting from the reaction of hydrazido-substituted or certain amino-substituted polymer stabilizers and cyclic dianhydrides, as well as the use of such products. The polymer stabilizers of the invention are useful for protecting a large variety of synthetic polymeric organic materials from the degradative effects of heat, light and oxygen. Some of the modifiers are flame retardants and many are metal deactivators in addition to their primary activity.
