Kinetic and degradation reactions of poly (sodium 4-styrene sulfonate) grafting “from” ozonized poly (ϵ-caprolactone) surfaces

The covalent grafting of poly (sodium 4- styrene sulfonate) on poly (ϵ-caprolactone) was proved to enhance the bioactivity of this polymer. The aim of this article was to perform kinetic studies of the activation and grafting processes and illustrate the influence of several parameters on the grafting rate and on the degradation of the polymer substrate. Results showed that the active groups created on poly (ϵ-caprolactone) surface by ozonation...
