- W2326515863 abstract "Atactic polypropylene was treated with chlorine gas in solution. The structure of the chlorinated polypropylene was investigated by means of infrared spectrophotometry.The chlorination in the sunlight proceeded by a chain reaction mechanism. Higher chlorinated products containing about 40% of chlorine were obtained under adjusted reaction conditions. The reactivity of the hydrogen atom in polymer was found to be in the order of CH<CH2<CH3. As the solvent, carbon tetrachloride and chloroform were more favorable than dichloroethane and trichloroethane. The chlorination in the presence of iodine or heavy metal in the dark seemed to undergo partially through ionic reaction mechanism, and the extent of chlorination rather decreased. In these cases, the methylene group in the polymer chain was most suspectible to the attack of chlorine. Crystallinity of polypropylene decreased with increase of the degree of chlorination." @default.
