PROCESS FOR MAKING MALEIC ANHYDRIDE POLYMERS WHICH INCLUDE MALEAMIC ACID AND/OR ITS CYCLIC IMIDE REPEAT UNITS

摘要

A process for making derivatized polymers of maleic anhydride containing maleamic acid and its corresponding cyclic imide repeat units, in alcohol solution, at a temperature of about 60-160 .degree.C, duri ng a reaction period of about 1-25 hours. The product is a polymer having a predetermined ratio of the above repeat units.
