The dithiocarbamate groups are known to act as photoinitiators in the free radical polymerization of vinyl monomers. The photolability of this group is due to the breaking of the C – S bond by UV irradiation. A photoinitiator, N,N-Diethyldithiocarbamato-(1,2)-propanediol (DCPD) was synthesized from sodium N,N-Diethyldithiocarbamate (SDDC) and 3-chloro-1,2-propanediol(CPD). A polyurethane macrophotoinitiator (PUCS) was then synthesized by a two step process where N,N-Diethyldithiocarbamato-(1,2)-propanediol was used as the chain extender. Other compounds used included 4, 4′- diphenyl methane diisocyanate (MDI), polypropylene glycol(PPG), M.W 1000. This polyurethane macrophotoinitiator having this pendent N,N-Diethyldithiocarbamato group was then used to polymerize 2-Hydroxyethyl methacrylate(HEMA) in a photochemical reactor (Compact- LP-MP 88) at 254 nm. The resultant graft copolymer, polyurethane-g-poly2-Hydroxyethyl methacrylate was freed from the homopolymer by a standard procedure. The graft copolymer was characterized by Fourier transform infrared spectroscopy, 1H- NMR spectroscopy, thermogravimetric analysis and scanning electron microscopy.
