Titrimetric studies of p-aminobenzoicacid-formaldehyde- p-bromophenol copolymers in non-aqueous media

Abstract

latter instance, the slope change also occurs at 1 M vinyl ether concentration. Such a feature implies that above this threshold [IBVE] monomer transfer assumes dominance over other chain breaking reactions. Monomer specificity n-Butyl vinyl ether and N-vinyl carbazole have also been observed to undergo facile polymerization in presence of C6HsCOC1 at ambient temperatures. For the polymerization of Nvinyl carbazole by C6H5COCI, as in the case with POC13, SOC12 and CrO2C12 no colouration was developed in the polymerization system or in the product polymer indicating the absence of charge transfer interactions is.
