摘要: Abstract The use of mineral acid to enhance the radiation grafting monomers trunk polymers such as polyethylene is shown be value for insolubilization enzymes and hetero-genization catalytically active homogeneous complexes. Two general methods are described showing how enhancement effects can used in immobilization reactions. In first technique, styrene grafted, resulting co-polymer nitrated followed by subsequent chemical reactions yield an appropriate substituent which attach ment processes occur. Alternatively, p-nitrostyrene grafted directly. latter method, valuable, since monomer deactivating any technique improving yields useful. effect also polyethylene, this backbone polymer less susceptible than other two studied, i. e., polypropylene ...
