PROCESS FOR IMPROVING THE CHEMICAL STABILITY OF NATURAL RUBBER LATEX WITH LOW AMMONIA CONTENT

摘要

THE INVENTION CONCERNS THE CHEMICAL STABILITY OF A NATURAL RUBBER LATEX WITH LOW AMMONIA CONTENT / P P THE CHEMICAL STABILITY OF LATEX AND LOW-AMMONIA NATURAL RUBBER LATEX FORMULATIONS IS IMPROVED BY THE ADDITION OF 0.1 TO 0.5% BY WEIGHT ON A SOLID BASE OF 100% BY WEIGHT OF SOLID BASED NATURAL RUBBER OF A SURFACTANT WHICH IS A NEUTRALIZED OR PARTIALLY NEUTRALIZED ANIONIC PHOSPHATE HAVING A PH OF 4 TO 10% THE FORM OF AN AQUEOUS SOLUTION AT 20. / P P THE RESULTING STABILIZED NATURAL RUBBER LATEX LATEX OR FORMULATIONS ARE PARTICULARLY SUITABLE FOR USE IN THE PREPARATION OF PREVULCANIZED SOFTENING FORMULATIONS. / P
