Method of making freely flowable composition of two rubbers

Claim 1

THE METHOD OF MAKING A FREELY FLOWABLE RUBBER COMPOSITION WHICH IS SMOOTH, LUMP-FREE AND FINE GRAINED WITH SUBSTANTIALLY ALL OF THE PARTICLES INVISIBLE TO THE NAKED EYE AND COMPRISING A HOMOGENEOUS TWO-PHASE LIQUID MASS CONSISTING ESSENTIALLY OF TWO RUBBERY ELASTIC MILLABLE POLYMERS HAVING DIFFERENT SOLUBLITY CHARACTERISTICS IN THE SAME SOLVENT, AND A VOLATILE ORGANIC LIQUID WHICH IS SOLVENT FOR ONE OF SAID POLYMERS AND A NON-SOLVENT FOR THE OTHER THEREOF, ONE OF SAID POLYMERS BEING DISSOLVED IN THE SOLVENT FORMING A SOLUTION AND THE OTHER BEING DISPERSED AS FINE, UNDISSOLVED PARTICLES IN THE SOLUTION, THE EXTERNAL PHASE BEING CONSTITUTED BY THE SOLUTION, AND COMPOSITION BEING CHARACTERISED BY THE FACT THAT MICROSCOPOC EXAMINATION AND ANALYSIS OF THE TWO RUBBERY COMPONENTS DERIVED BY DILUTING AND CENTRIFUGING THE FLUID COMPOSITION SHOWS THAT ONE COMPONENT CONSISTS OF RUBBER IN THE FORM OF PARTICLES WHICH, ALTHOUGH THEY MAY BE SWOLLEN, ARE STILL DISCRETE AND CLEARLY VISIBLE WHILE EXAMINATION OF THE OTHER COMPONENT FAILS TO SHOW ANY PARTICLES AT ALL, COMPRISING INTERMILLING TWO OF SAID POLYMERS, SAID TWO POLYMERS BEING INITIALLY SEPARATE, SUBJECTING THE MILLED MASS TO MECHANICAL TREATMENT IN THE PRESENCE OF THE ORGANIC LIQUID, AND CONTINUING THE MECHANICAL TREATMENT IN THE LIQUID UNTIL THE INSOLUBE RUBBER IS DISRUPTED AND DISPERSED IN THE FORM OF DISCRETE PARTICLES SUSPENDED IN THE SOLUTION OF THE SOLUBLE RUBBER.
