Isotactic polypropylene fiber (IPP) was graft-copolymerized using 2-vinyl pyridine (2-VP) and styrene (sty) as the monomers by the mutual irradiation method in air. The percentage of grafting was determined as a function of various reaction parameters and it was found that the maximum grafting of 2-
The photochemical grafting of styrene onto polypropylene (PP) using benzophenone (BP) and benzoin ethyl ether (BEE) as photosensitizers is described. The effects of various parameters (such as monomer and photosensitizer concentration, reaction time, and solvent) on percent grafting were studied. We
## Abstract A method of graft copolymerization of hydrophilic monomers, such as 1βvinylβ2βpyrrolidone, acrylonitrile, acrylic acid, and acrylamide, onto irradiated polypropylene fibers has been studied. Ξ³ ray as well as electron beam were employed for the irradiation processes. Graftβcopolymerizati
Polypropylene (PP) Γlms were grafted with N-phenylmaleimide using c-radiation. The e β ect of both monomer concentration and dose rate on the degree of grafting was measured. Characterization of the grafted PP Γlms included IR spectroscopy, X-ray spectroscopy, electrical conductivity, mechanical prop
