Modification of polypropylene fiber was carried out by graft copolymerization of acrylonitrile monomer using the preirradiation method. The influence of synthesis conditions (preirradiation dose, monomer concentration, temperature, draw ratio, and storage) on the degree of grafting was investigated.
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-
Polypropylene (PP) รlms were grafted with N-phenylmaleimide using c-radiation. The e โ ect of both monomer concentration and dose rate on the degree of grafting was measured. Characterization of the grafted PP รlms included IR spectroscopy, X-ray spectroscopy, electrical conductivity, mechanical prop
