✦ Synopsis

Copolymers of poly ( acrylamide-co-acryloyloxyethyltrimethylammonium chloride or AM-CMA) and poly (acrylamide-co-methacryloyloxyethyltrimethylammonium chloride or AM-CMM ) prepared by inverse emulsion polymerization were characterized by different analytical techniques. The chemical composition of the copolymers was estimated by elemental analysis and by nuclear magnetic resonance spectroscopy (NMR) . NMR spectroscopy and computer simulation were further used for investigating the polymers' sequence distribution. The poly( AM-CMA) copolymers are chemically more homogeneous than are the poly( AM-CMM) . The configurational propagation of dyads and triads for the homopolymers obeys Bernouilli's statistics. For the copolymers, the chemical sequences distribution is governed by Markov's first-order statistics.
