Abstract
AbstractThe copolymerisation of styrene and 2‐hydroxyethyl methacrylate (2‐HEMA) in a three‐component oil‐in‐water microemulsion containing sodium dodecylsulfate as emulsifier was investigated as a function of temperature and concentration of potassium persulfate or hydrogen peroxide/ascorbic acid as initiator. Stable and transparent poly(styrene–2‐HEMA) latexes were produced. The latexes were characterised for particle size and number of particles by dynamic light scattering and transmission electron microscopy. The isolated products were characterised by 1H NMR as well as by thermal analysis. The overall size of particles was observed to be in the range 22–38 nm. Attempts are made to examine the suitability of the existing mathematical models for homopolymerisation to account for the copolymerisation of styrene and 2‐HEMA.© 2002 Society of Chemical Industry
