ABSTRACT:
A novel method of preparing polymers in aqueous medium involves the free radical initiated addition polymerization of the monomer or monomers from which the polymer is formed in an aqueous medium in the presence of a non-salt forming free radical polymerization initiator and a salt or partial salt of an acid-containing polymer containing one or more pendent double bonds. The pendent double bonds of the acid containing polymer provide a convenient grafting site for the polymer being formed by the free radical polymerization.
The novel method of the invention provides for excellent stability and compatibility of the resultant aqueous based polymer.
