Mixed micelles of cetyltrimethylammonium bromide and poly(ethylene glycol)-600 monolaurate as catalysts of polyethylenimine phosphorylation in chloroform

摘要

Micelle formation in a cetyltrimethylammonium bromide-poly(ethylene glycol)-600 monolaurate-chloroform system in the absence and presence of hydroxybenzylated poly-ethylenimines (PEI) was studied by dielcometric titration,NMR self-diffusion,light scattering,and kinetic methods.A catalytic effect of mixed micelles on the reaction of 4-nitro-phenylbis(chloromethyl)phosphinate with PEI was shown.The catalytic effect depends on the degree of substitution of PEI and composition of a surfactant mixture.
