US4622356A - Polyacrylamide and polyacrylic acid polymers

The use of a cyclic compound containing a ##STR1## group, i.e., methone, has been found to allow a poor acrylamide or acrylic acid or 2-acrylamide-2-methylpropane sulfonic acid and its salts monomer to be polymerized to a polymer having improved performance characteristics and/or improved rates of polymerization.

Synthesis and characterizing a novel polymeric flocculant

The article highlights the development of a new generation of polymeric flocculant by grafting binary monomer mixture of acrylamide and acrylic acid onto a natural polymer—amylopectin [(AP-g-PAM)-g-PAA]. Primary graft copolymerization of acrylamide onto AP and binary graft copolymerization of acrylic acid onto AP-g-PAM was accomplished in 84 and 91 % grafting efficiency (% GE) using
