Vinyl polymers containing amido and carboxylic groups as side substituents. I. Synthesis of N-acryloyl-glycine and N-acryloyl-6-caproic acid and their grafting on cellulose membranes

Two vinyl monomers containing amido and carboxylic groups, namely N-acryloyl glycine and N-acryloyl-6-caproic acid, have been synthesized and polymerized by radical initiators. The polymers of high molecular weight were prepared in a dioxane solution by radical polymerization of the corresponding monomers. Graft copolymers of both monomers on cellulose films have been obtained by use of ceric salts. The surface modifications of the grafted cellulose films have been checked by attenuated total reflection/FT i.r. spectra. The difference spectra of the surface graft polymers were found to be very similar to those of the homopolymers.
