Abstract
The present invention relates to a process for functionalising polymer materials, comprising a first step wherein the polymer material is grafted, by means of high energy irradiation, with a functionalised monomer having at least one first functional group and at least one olefinic end group, and a second step wherein the so-treated polymer material is reacted with a functionalised organic compound having at least one second functional group reactive with respect to said first functional group, in the presence of an enzymatic catalyst. The coupled functionalised compound is able to impart specific properties to the polymer matrix, such as antibacterial or flame retardant properties, or can be employed to produce biocomposites to be used, for instance, in the biomedical field, or in the food, construction, packaging or textile industries.
