Styrene-butyl acrylate copolymers functionalized with glycidyl methacrylate have been produced by emulsion polymerization using either a batch terpolymerization process or a semi-continuous process, in some cases with delayed addition of the glycidyl monomer. The location of the epoxy groups has been studied by surface analysis using soap adsorption methods, and also by kinetic analysis of the results of titration with HCl. It has thus been possible to analyse the distribution of the epoxy groups inside the particle. The crosslinking reaction was carried out with hexamethylene diamine introduced into the latex just before use; film formation was by simple water evaporation and was followed by maturing of the films for up to 6 weeks at room temperature or by thermal treatment for 12 h at 100-degrees-C. The crosslinking process was followed by swelling experiments or by measurement of the mechanical properties. These mechanical properties are very dependent upon the radial distribution of the glycidyl monomer units, which is itself governed by the polymerization process. The material may be viewed as a highly crosslinked network with soft, poorly crosslinked, inclusions.
