ABSTRACT:
A method of treating synthetic polyisoprene and styrene butadiene latices comprising adding to the latex particular redispersing agents so that the solid rubber obtained when the water is removed from the latex is redispersible. Various redispersing agents are described including urea with supplementary agents. Reconstituted latices obtained from such redispersible solid rubbers have comparable properties with freshly prepared latices.
