HOFMANN REARRANGEMENT IN CROSS-LINKED POLYSTYRENE MATRICES

Hofmann rearrangement has been carried out in polymeric amides synthes ised from styrene-divinylbenzene (DVB) copolymer. A series of crosslin ked copolymers with varying crosslink densities have been prepared by adjusting the monomer/crosslinker ratio. The amide function is introdu ced into the polymer matrix through a series of polymer-analogous reac tions. These are treated with sodium hypobromite in the presence of ex cess alkali. The products have been characterized by elemental analyse s and spectral data. A temperature dependent relation between rearrang ement and hydrolysis has been observed.
