    摘要： Chlorinated organic compounds having their resistance to deterioration (when heated, exposed to light or water, or in contact with certain metals such as iron and aluminum) enhanced by a 1,3-dicarbonyl compound having the formula: ##STR1## wherein: R.sub.1 is selected from the group consisting of hydrogen, hydrocarbon groups having from one to about eighteen carbon atoms and such groups substituted with one or more groups selected from the group consisting of halogen, hydroxy, alkoxy OR.sub.1, ester COOR.sub.1, alkyl and alkoxycarbonyl alkyl having from one to about eighteen carbon atoms;R.sub.2 is selected from the group consisting of hydrocarbon groups having from one to about eighteen carbon atoms and such groups substituted with one or more groups selected from the group consisting of halogen, hydroxy, alkoxy OR.sub.1, ester COOR.sub.1, alkyl and alkoxycarbonyl alkyl having from one to about eighteen carbon atoms;R.sub.3 is selected from the group consisting of hydrogen, hydrocarbon groups having from one to about eighteen carbon atoms and such groups substituted with one or more groups selected from the group consisting of halogen, hydroxy, alkoxy OR.sub.1, ester COOR.sub.1, alkyl and alkoxycarbonyl having from one to about eighteen carbon atoms; and ##STR2## provided, when both R.sub.3 are hydrogen, at least one R.sub.1 and R.sub.2 is other than methyl as well as metal and organotin enolate salts thereof. The compounds are effective in enhancing the resistance to deterioration of chlorinated hydrocarbons and chlorinated higher fatty acid esters.

    摘要： The present invention provides a method of producing a chlorinated rubber wherein an acidic or highly acidic chlorinated rubber cake obtained after chlorinating a rubber latex or an aqueous dispersion is subjected to fluidized drying together with a drying medium to obtain a preliminary dried powder, and the preliminary dried powder is subjected to fluidized drying again. According to the present invention, a high quality chlorinated rubber can be obtained efficiently with easy handling from an acidic or highly acidic chlorinated rubber cake obtained after chlorinating a rubber latex or an aqueous dispersion.
