Production of Radiation Cross-Linked Cellulose-Based Polymeric Materials*

The process of radiation grafting of polymeric materials to cellulose in the presence of dyes was studied. It was found that among the tested dyes rhodamine 6G has the best resistance to γ-irradiation. The radiation-grafted copolymer with rhodamine 6G is characterized by a high color stability, which persists even after prolonged Soxhlet extraction with water and hydrocarbons. The tested method of obtaining radiation-grafted materials can be used to obtain biodegradable colored packaging materials.
