Cure grafting - a complementary technique to preirradiation and simultaneous processes?

A novel radiation grafting process, termed cure grafting, based on curing of donor/acceptor (DA) monomers as charge transfer complexes initiated by UV or any ionising radiation source, is proposed. The system is complementary to the existing preirradiation and simultaneous radiation grafting methods. The advantages and disadvantages of cure grafting are summarised. Examples of cure grafting using representative DA monomers are described with cellulose as model substrate in the presence of UV or EB. A unique property of cure grafting is that the yield is known quantitatively prior to irradiation
