In addition polymerization, the monomer need have only one functional group - the presence of two or more functional groups usually leads to the production of cross-linked addition polymers.
By the method of free-radical polymerization in solution, cross-linked copolymer of sodium acrylate and acrylic acid of super-high molecular weight.
