With glutin(GEL) which was a gelatine material in ancient ink-sticks as main material,butyl acrylate(BA) and acrylonitrile(AN) as assistant material,a graft modification glutin adhesive for repairing damaged ancient ink-sticks was synthesized by inverse emulsion graft copolymerization under mix conditions of two types non-ionic emulsifier.

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.
