Abstract
Method of grafting a water-soluble organic oligomer(s) to an organic polymer(s) in aqueous latex form, which method comprises forming a water-based mixture of a water-soluble oligomer(s), an aqueous latex of a polymer(s), and at least one free radical polymerisable monomer, both of said oligomer(s) and polymer(s) being preformed, and carrying out free radical polymerisation of said at least one monomer to effect grafting between said oligomer(s) and said polymer(s).
