| Abstract: | Grafting copolymerization of styrene and acrylic acid onto polypropylene fabric had been studied by using a
pre-irradiation technique. The polypropylene fabric samples were irradiated by γ -ray and electron beam under the conditions of air
and nitrogen gas, respectively. The effect of absorbed dose, monomer concentration in solvent, reaction temperature and reaction time
on the degree of grafting were determined. The effects of metallic salts and sulphuric acid on the grafting yield of acrylic acid were
also examined. The samples irradiated by electron beam give a much higher degree of grafting than those by γ -ray when styrene was
grafted to polypropylene fabric. However, the grafting yield of acrylic acid on polypropylene fabric in the presence of metallic salts
and sulfuric acid showed the opposite results from the case of styrene. This effect is reasonably interpreted by assuming that the
grafting is dominated by trapped radicals and peroxides in pre-irradiated polypropylene. |
