PROCESS FOR DEPOLYMERIZATION OF BUTYL RUBBERS AND HALOBUTYL RUBBERS USING HOT LIQUID WATER |
| 摘要 |
The present invention relates to a process for depolymerizing and dehalogenating rubber materials by heating the rubber materials with neutral liquid water at temperatures from about 200.degree.C up to the critical temperature of water at autogenous pressure. The process has utility in degrading rubber materials, and further does not release hydrogen halogen into a gas phase.
