Halamine polymers: 1. Preparation and characterisation of new pyrimidinone biocidal polymers based on poly‐4‐vinylacetophenone

Abstract

A series of novel halamine polymers known as pyrimidinone biocidal polymers were prepared by reacting poly‐4‐vinylacetophenone with urea and benzaldehyde to form 1H,3H,6H,‐4(4′‐polystyreno)‐6‐phenyl‐pyrimidin‐2‐one, which on chlorination yielded 1Cl,3H,6H,‐4(4′‐polystyreno)‐6‐phenyl‐pyrimidin‐2‐one. The same reaction was also carried out using the derivatives of benzaldehyde such as p‐nitrobenzaldehyde and p‐methoxybenzaldehyde under the same reaction conditions. .
