Radiation technologies used on industrial scale has been continuously developing for over 60 years. Ionizing radiation (gamma, X-ray and electron beam – EB) is used for modifying the properties of materials (crosslinking, degradation, radiation-induced grafting), sterilization of medical devices and tissue grafts and for environmental protection. By applying radiation technologies new specyfic properties of materials can be introduced by radiation-induced grafting of different types of monomers or modification of polymer physicochemical properties.
This report presents two examples of polymer modification by EB irradiation. The first part of the work involves surface modification of selected polymers by radiation-induced grafting whereas the second part includes radiation-induced modification of degradable copolymers based on aliphatic polyester.
