Graft copolymers(SPI-g-NH-PAMPS)were prepared by a graft reaction between the free carboxylic acid groups of soy protein isolate(SPI)and the amino groups of poly(2-acrylanmido-2-methyl propane sulfonic acid)(H_2N-PAMPS)using 1-(3-(dimethylamino)propyl)-3-ethyl-carbodiimide hydrochloride/N-hydroxysuccinimide as the condensing agents in a buffer solution.

The results showed that the product was grafted copolymer of cellulose acetate and poly(actic acid),and poly(actic acid) side chains were detected in the copolymer.

Polycarboxylate grafted copolymer used as superplasticizer was synthesized first through free radical copolymerization of acrylic acid and sodium allyl sulfonate to prepare copolymer containing carboxyl and sulfonic group,then esterification with polyethylene glycol monoalkyl ether.

The grafted copolymers of methyl methacrylate (MMA) and CPE as the compotilizer of the PVC/CPE blends are discussed.
