PROCESS FOR THE PREPARATION OF IMIDIZED ACRYLIC POLYMERS

摘要

Imidized acrylic polymers obtained by reacting an acrylic resin in the molten state with at least one modifier of the formula: wherein R min , R sec and R''', the same or different, are hydrogen or an alkyl, cycloalkyl, aryl, alkylaryl or arylalkyl radical containing from 1 to 20 carbon atoms, X is an alkylene radical, straight or branched, containing from 1 to 12 carbon atoms, a cycloalkylene radical containing from 5 to 12 carbon atoms or an arylene radical containing from 6 to 12 carbon atoms, optionally substituted with heteratoms such as O, N, S, halogen, etc.
