Abstract: A PROCESS IS DISCLOSED FOR PREPARING A POLYMERIC LATEX FROM AN AQUEOUS EMULSION OF A SOLUTION OF A POLYMER WHEREIN THE EMULSION IS BROUGHT INTO CONTACT WITH A SOLID SUCH AS CURED AND CROSS-LINK 1,4,-CIS-POLYBUTADIENE IN A FORM WHICH PROVIDES A HIGH SURFACE/VOLUME RATIO SO THAT THE SOLVENT FOR THE POLYMER IS ADSORBED BY THE SOLID WHICH IS THEN REMOVED FROM THE RESULTING LATEX. THE PROCESS IS CARRIED OUT AT A TEMPERATURE WHICH IS BELOW THE BOILING POINT OF THE SOLVENT FOR THE POLYMER AND THE SOLID USED AS AN ADSORBENT IS COMPATIBLE WITH, BUT INSOLUBLE IN, THE SOLVENT FOR THE POLYMER AND IS INCOMPATIBLE WITH THAT POLYMER.

Abstract: A polyethylene is disclosed that is modified by copolymerizing ethylene with a comonomer consisting of a minor quantity of a polycyclic polyene having at least three double bonds in the molecule, and preferably an endomethylenic bridge, so that it can be readily cross-linked under the influence of heat without the presence of an additive, but which still exhibits the characteristics of a conventional crystalline polyethylene.
