Abstract
A natural rubber latex has been preserved and stabilized by at least one water-soluble carboxylic acid salt of the formula R--COO.sup.- M.sup.+, in which R is an alkyl or alkenyl radical having a branched carbon chain and M.sup.+ is a monovalent cation. A process for the preparation of the rubber latex mixture uses a water-soluble carboxylic acid salt for the preservation and stabilization of natural latex.
