Continuous process for chemically modifying iso-olefin-multiolefin rubbery polymer

Claim 1

IN THE CONTINUOUS PROCESS FOR MAKING AND RECOVERING A RUBBERY POLYMER OF A MAJOR PROPORTION OF A C4 TO C7 ISOOLEFIN WITH A MINOR PROPORTION OF A C4 TO C14 MULTIOLEFIN MADE BY CONTINUOUS FRIEDEL-CRAFTS POLYMERIZATION WHICH IS A FIRST NON-SOLVENT FOR THE POLYMER THEREFROM, WHEREBY THERE IS CONTINUOUSLY PRODUCED A POLYMERIZATION REACTION FIRST SLURRY DISPERSED IN A LIQUID MEDIUM CONSISTING ESSENTIALLY OF SAID ALKYL HALIDE DILUENT, THE IMPROVEMENT WHICH COMPRISES; CONTACTING SAID FIRST SLURRY AT A TEMPERATURE ABOVE THE BOILING POINT OF SAID SLURRY WITH A C5 TO C10 LIQUID HYDROCARBON SOLVENT FOR THE POLYMER TO VOLATIZE SAID DILUENT THEREFROM AND TO DIRECTLY DISSOLVE POLYMER THEREIN WHILE MAINTAINING THE TEMPERATURE BETWEEN 20 AND 100*C., SAID SOLVENT BOILING ABOVE THE BOILING POINT OF SAID DILUENT; REACTING THE POLYMER IN SOLUTION CHEMICALLY BY INCORPORATING INTO SAID SOLUTION A MATERIAL SELECTED FROM THE GROUP CONSISTING OF SULFENYL HALIDES, SELENENYL HALIDES, N-NITROSO-P-NITROSO ALKYL ANILINE, AZOMONOCARBOXYLATED, AZODICARBOXYLATES, C1 TO C10 ALIPHATIC, ALDEHYDES, C1 TO C10 AROMATIC ALDEHYDES, A HALOGEN AND MIXTURES THEREOF; CONTACTING SAID SOLUTION HAVING SAID CHEMICALLY REACTED POLYMER THEREIN WITH A SECOND NONSOLVENT AQUEOUS LIQUID MEDIUM AT A TEMPERATURE ABOVE THE BOILING POINT OF SAID SOLVENT TO VOALATIZE SOLVENT THEREFROM AND TO FORM A SECOND SLURRY OF COPOLYMER IN SAID SECOND NON-SOLVENT, SAID SECOND NON-SOLVENT BOILING RECOVTHE BOILING POINT OF SAID SOLVENT; AND SUBSEQUENTLY RECOVERING SAID REACTED POLYMER FROM SAID SECOND SLURRY.
