Abstract
N-substituted acrylamidines, a new class of acrylic monomers, are synthesized by the process of this invention which comprises successively contacting with an acrylonitrile or derivative thereof (a) a Lewis acid catalyst, (b) an alkyl halide and (c) an amine. Novel polyacrylamidines as well as quaternary salts of polyacrylamidines are disclosed. Due to their basic nature the N-substituted acrylamidines are useful for introducing basic groups into polymers.
