Radiation grafting of N,N-dimethylaminoethylmethacrylate and 4-vinylpyridine onto polypropylene by the one- and two-step methods

Abstract:

Radiation grafting of N,N-dimethylaminoethylmethacrylate (DMAEMA) and 4-vinylpyridine (4-VP) from the 50% monomers solutions in toluene and dichloroethane onto polypropylene (PP) films was carried by their mutual γ-irradiation (one-step method). In the two-step method, the grafting of DMAEMA or 4-VP from their solutions in toluene was performed onto PP modified preliminary with the other polymer (poly4-VP or polyDMAEMA). It has been found that chemical structure of PP modified with the first grafted polymer affected the efficiency of the other monomer grafting by the second step.
