Title: Improvements in or relating to chlorinated rubber manufacture
IPC: C08C19/12
Filed: 1956-03-05
Abstract: Chlorinated rubber is prepared by reducing by over 95 per cent the viscosity of a solution of rubber in a solvent substantially inert to chlorine by treating it with a stream of a carrier gas substantially inert to chlorine dioxide containing up to 9 per cent by weight of chlorine dioxide, and subsequently chlorinating the rubber solution at a temperature between 25 and 70 degrees centrigrade until chlorinated rubber having about 66 per cent by weight of chlorine is produced.  The carrier gas may be air, nitrogen, waste combustion gases from boilers, neon, helium, or argon.  The initial rubber solution, preferably contains 4 to 8 per cent by weight of rubber, which may be crepe, smoked sheet, or a synthetic rubber, the preferred solvent being carbon tetrachloride.  Other solvents specified are tetrachloroethane, ethylene dichloride, and chloroform. In one example 920 lbs. crepe rubber is digested in caustic soda solution, washed, and dried, as described in Specification 523,749 and milled for 10 minutes on heated rolls.  A solution of the digested and milled rubber in carbon tetrachloride, and containing 4,4 per cent by weight of rubber is maintained at 31 DEG C. whilst passing thereinto a stream of air containing 4,9 per cent by weight of chlorine until the viscosity of the solution is reduced to approximately 1,16 per cent of its original volume.  The resulting solution was then treated with chlorine at a temperature slightly under 70 DEG C., and the chlorinated rubber precipitated by adding hot water.  In other examples the initial rubber solutions are of undigested crepe rubber and of both milled and unmilled digested crepe rubber of various concentrations.  Specifications 574,834 and 574,835 also are referred to.
