RADIATION GRAFTING OF VINYL MONOMERS TO POLYOLEFIN FIBERS

OSTI ID:4125640
The results of an experimental investigation on a method for producing grafted polyolefins using pre-radiation to reduce or eliminate formation of homopolymer are presented. A method was developed for the graft polymerization of a series of vinyl monomers to polypropylene fibers subjected to preliminary gamma radiation from Co/sup 60/ in the presence of air. It was found that an increase in radiation of polypropylene and polyethylene fibers raises the content of peroxide groups resulting in a simultaneous reduction in strength and elongation of the fiber. In the presence of a 3-4 fold excess of ferrous sulfate with respect to the peroxide groups, the graft polymerization of acrylic acid and 2-methyl-5-vinylpyridine to previously irradiated polypropylene fiber containing an antioxidant proceeds without formation of the homopolymer. In the graft polymerization of acrylonitrile, the formation of a small quantity of homopolymer is observed. (OTS)
