In order to evaluate the anionic grafting reaction for monomers which are prone to chain transfer termination, a study was made of the graft polymerization of acrylonitrile on the potassium alkoxide derivative of starch and dextrin in dimethylsulphoxide. The effects of monomer and alkoxide concentra

The anionic graft polymerization of 4-vinyl pyridine on the potassium alkoxide derivative of starch or dextrin in dimethyl sulphoxide solution was studied. Graft polymerization occurred only at relatively high alkoxide concentration. The yields of pure graft polymer were low due to extensive homopol
Graft copolymers of ethylene-propylene terpolymers (EPDM) have been prepared by metallation of EPDM with a lithium butyl/potassium t-butoxide complex and subsequent addition of styrene or butadiene. Carboxylated polymers have been produced by reacting metallated EPDM with carbon dioxide.
Graft polymers of polyformaldehyde on starch, dextrin and polyvinyl alcohol were obtained by polymerizing formaldehyde monomer on the alkoxide derivative of the polyhydroxy polymers in dimethylsulphoxide solution.
