发现某些无机盐水溶液有利于NVP的交联聚合反应

并用“笼蔽效应”作了解释 .

Abstract

In this paper

the influences of solvents

monomer conncentration and initiator concentration on radical polymerization of N -vinylpyrrolidone(NVP) are investigated. Especially

benzene

ethanol

distilled water are experimented as solvents to investigate the influences of solvent polarities

viscosities of mixture of monomer and solvent on polymerization rate

chain propagation rate and relative molecular mass of polyvinylpyrrolidone. Furthermore

crosslinking polymerization properties of N -vinylpyrrolidone and N

N - methylenebisacrylamine(NNMP) are studied. It is found that a higher yield of crosslinking polyvinylpyrrolidone(PVPP) can be obtained in a aqueous solution of some inorganic salt. Some explanations are presented.
