The role of solvents in photografting a typical methacrylate monomer, methyl methacrylate (MMA)
to polypropylene (PPE) and cellulose is reported. A wide range of solvents of varying polarities
have been studied for grafting to these substrates. The effect of additives which represent typical
components used in radiation curing on the grafting reaction is examined. Additives studied
include vinyl ethers, divinyl benzene (DVB), epoxy acrylate (EA), and diethylene glycol dimethacrylate (DEGDMA). These solvent studies have been extended to include grafting with charge transfer (CT) complexes involving donor- acceptor (DA) monomers to PPE, cellulose and wool. The importance of this work in analogous curing processes is discussed, particularly the significance of concurrent grafting during curing.
