Process for synthesizing poly(spermine acrylamide) and/or poly(spermine acrylamide-co-n-alkylacrylamide) and their application

Abstract

The present invention relates to a process for the synthesis of poly(spermine acrylamide) and/or poly(spermine acrylamide-co-N-alkylacrylamide), the process comprising the following steps: a) reacting a mixture of N-acryloxysuccinimide with N-alkylacrylamide, and b) obtaining poly(N-acryloxysuccinimde) polymers, poly(N-alkylacrylamide) polymers and/or copolymers with varying ratios of N-acryloxysuccinimide and N-alkylacrylamide, and c) treating the obtained polymers and/or copolymers of step b) with at least 0.1 equivalent of tri-boc spermine per N-acryloxysuccinimide-repeating unit and obtaining poly(spermine acrylamide) and/or poly(spermine acrylamide-co-N-alkylacrylamide) polymers.
