Abstract: | The free-radical copolymerization of N-vinylpyrrolidone with N,N-diallyl-N′-acetylhydrazine and N,N-diallyl-N′-butanoylhydrazine has been investigated in bulk and solution. The copolymerization yields random copolymers enriched with N-vinylpyrrolidone units. The kinetic study of the reaction has revealed that the rate of copolymerization decreases with a rise in the fraction of an allyl monomer in the initial monomer mixture. Both double bonds of diallylacylhydrazines are involved in the copolymerization to give rise to five-membered pyrrolidine rings. |
