Abstract

This method determines the volatile fatty acid number of natural rubber latex which contains preservative agents and which has been submitted to some type of concentration process. The method is not necessarily suitable for latices from natural sources other than Havea brasiliensis, and is not applicable to compounded latex, latex, vulcanized latex, artificial dispersions of rubber or synthetic rubber latices.
