| 摘要 | PURPOSE: To decompose a vulcanized rubber efficiently even at low temp. of 100°C or below, by mixing an org. hydroperoxide and at least one member selected from a copper salt, a cobalt salt and a strong alkali compd. with the vulcanized rubber. CONSTITUTION: 100pts.wt. vulcanized rubber is swelled in 10W3,000pts.wt. org. solvent. Then 0.1W20pts.wt. org. hydroperoxide (A) and 0.001W1mol equivalent (based on the amount of A) of at least one member selected from a copper salt, a cobalt salt and a strong alkali compd. are mixed with said swelled rubber in said solvent. Examples of said org. hydroperoxides are tertbutyl hydroperoxide and cumene hydroperoxide. Examples of said copper salts are cuprous chloride and cupric chloride. Examples of said cobalt salts are cobalt naphthenate and cobalt octenoate. Examples of said strong alkali compds. are lithium hydroxide and sodium hydroxide. COPYRIGHT: (C)1981,JPO&Japio |
