ABSTRACT:
A variety of graft copolymers can be formed sodium poly(aspartate) with a wide variety of monomers in an aqueous medium by the use of grafting method in the presence of radical initiator at a temperature of from about five degrees Centigrade to about 100 degrees Centigrade. Graft copolymers at high conversion with molecular weight up to millions can be prepared using this method.
