Radiation Induced Graft Copolymerization of Styrene on to Nylon 6 (in Japanese)

Journal Article · · Kobunshi Kagaku (Chemistry of High Polymers)
; ;
The effects of irradiation atmosphere, dose rate, solvent, and solvent/ monomer ratio on the grafting of styrene to nylon 6 film were studied. It was found that the induction period of the grafting in the presence of alr was very short. The amount of grafted polystyrene after an integrated dose of 1.0 x 10/ sup 5/ roentgens was inversely proportional to the square root of the intensity between 50 and 2000 roentogen/ min. The effect of the solvent on the grafting was very remarkable. Organic solvents studied in this experiment were methanol, ethanol, n-butanol, sec-butanol, tert-butanol, isobutanol, benzene, acetone, carbon tetrachloride, dimethylformamide and m-cresol. The addition of 1% water or 3% methanol to the grafting mixtures noticeably accelerated the rate of grafting. The lower the carbon chain length of aliphatic alcohol, the more effective was the acceleration of the grafting. In styrene-alcohol mixtures three maxima of the amount of grafting were observed for monomer/ solvent ratio. In the mixture of styrene and organic solvent except methanol, a slight or no increase of acceleration was observed. Some experiments on the grafting of styrene in the presence of divinylbenzene were also carried out.
