Abstract
The chemical stability of low ammonia natural rubber latices and latex compounds is improved by the addition of from 0.1 to 0.5 parts by weight solids, per 100 parts by weight of natural rubber solids, of a neutralized or partially neutralized anionic phosphate surfactant having a pH in a 20 percent aqueous solution of from 4 to 12. The resultant stabilized natural rubber latices or latex compounds are particularly suitable for use in preparing prevulcanized dipping compounds.
