چکیده انگلیسی
Methyl methacrylate (MMA) was graft copolymerized onto Bombyx mori fibre (natural silk). The graft copolymerization was carried out by photopolymerization of MMA using semiconductor particles (CdS) as photocatalyst in the presence of visible light. The effect of additives like triethylamine (Et3N) and ethylene glycol on graft copolymerization was studied. We have achieved 2–10% graft conversion with 10–20% homopolymer formation. After removal of the homopolymer, the graft copolymer (grafted fibre) was characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC). The chemical resistance of grafted fibre was compared with virgin one.
