Abstract

A METHOD FOR REDUCING THE MOLECULAR WEIGHT OF RUBBER IN LATEX FORM OR IN WET COAGULUM FORM COMPRISES TREATING THE LATEX WITH AN OXIDIZING AGENT AND A REDUCING AGENT. THE OXIDIZING AGENT IS AIR, OXYGEN OR A PEROXIDE AND THE REDUCING AGENT IS A METAL NITRITE AND/OR A METAL CHLORITE.@@THE METHOD IS PARTICULARLY SUITED FOR USE WITH NATURAL RUBBER LATEX, INCLUDING EPOXIDIZED NATURAL RUBBER LATEX. DEPENDING UPON THE DEGREE OF REDUCTION OF THE MOLECULAR WEIGHT, THE METHOD MAY BE USED I) IN THE PREPARATION OF LIQUID RUBBER, II) IN THE PREPARATION OF IMPROVED LATEX ADHESIVES AND III) IN THE CONTROL OFTHE VISCOSITY OF RUBBER DURING NORMAL PRODUCTION.
