AbstractThe gamma radiation‐induced surface graft copolymerizations of styrene—acrylonitrile and styrene—methyl acrylate to Teflon were studied. It was observed that the compositions of the various grafted copolymers are richer in the more polar monomer than one would predict from the Lewis‐Mayo copolymer composition equation.

Graft Copolymerization of Wool Fibers
Journal of Macromolecular Science, Part C: Polymer Reviews, 1992Abstract Modification of the properties of natural and synthetic polymers through graft copolymerization has been a subject of interest of researchers for the last few decades. Grafting reactions provide a potential route for significantly altering the physical, mechanical, and biochemical properties of such polymers [1, 2].

The kinetics of graft copolymerization
Journal of Polymer Science, 1959AbstractGamma‐ radiation induced graft copolymerization of methyl methacrylate with natural rubber is characterized by high yields of grafted polymer even at relatively high monomer concentrations. The rates are first order except at low monomer concentrations; above 95% rubber concentration the polymerization rates are very low.

Characteristics of Heterophase Graft Copolymerizations
Journal of Macromolecular Science, Part A, 1992Abstract Persulfate-initiated graft copolymerizations of glutaraldehyde crosslinked gelatin with acrylic acid, acrylamide, vinyl acetate, and methyl methacrylate in the aqueous phase were investigated. It was observed that percentage grafting, molecular weights of the grafts, and grafting efficiencies were greatly influenced by the nature of the ...

AbstractThe radiation induced graft copolymerization of methylacrylate onto nylon‐6 fiber at room temperature and in nitrogen medium was investigated. The effects of monomer, dose rate, inhibitor etc. on the graft yield have been investigated. The effect of solvents on the rate of grafting was studied from which the chain‐transfer constant (Cs) of the ...

AbstractPhoto‐induced graft copolymerization was investigated using nitrocellulose having a different nitrogen content, especially by a noncatalytic method. The effects of a sample nitrogen content, reaction temperature, and monomer, sample, solvent and photosensitizer concentrations on the degree of grafting, the grafting efficiency, and the apparent ...

AbstractPolyacrylonitrile–β‐propiolactone (βPL) graft copolymer was synthesized by means of ionic polymerization, in which polymerization of βPL was initiated by polyacrylonitrile containing a small amount of some reactive groups such as COOK, COONa, COOLi, and COOH.
