Milling rubbery hydrocarbon polymer with resinous residue from polymerization of cracked gasoline

Claim 1

AN IMPROVED METHOD FOR COMPOUNDING A SOLID RUBBERY HYDROCARBON POLYMER OF A CONJUGATED DIENE, COMPRISING MILLING SUCH A HYDROCARBON POLYMER AT A TEMPERATURE WITHIN THE RANGE OF 50 TO 350*F. AND DURING SAID MILLING ADDING TO SAID HYDROCARBON POLYMER A SOLID RESINOUS PRODUCT SEPARATED AS A DISTILLATION RESIDUE FROM A LIQUID POLYMERIC MATERIAL PRODUCED BY A MIXED PHASE POLYMERIZATION OF UNREFINED CRACKED GASOLINE AT A TEMPERATURE IN THE RANGE OF 250 TO 750*F., AT A PRESSURE IN THE RANGE OF 50 TO 600 P.S.I.G., AND IN THE PRESENCE OF A CONTACT MASS COMPRISING A CLAY; SAID RESINOUS PRODUCT COMPRISING FROM 3 TO 20 PER CENT BY WEIGHT OF A RESULTING SOLID RESINOUS PRODUCT-HYDROCARBON POLYMER, AND CONSISTING OF 100 PER CENT NONVOLATILE MATTER AS MEASURED FOR A DURATION OF 3 HOURS AT A TEMPERATURE OF 225*F. AT ATMOSPHERIC PRESSURE, AND HAVING AN IODINE NUMBER IN THE RANGE OF 200 TO 300, A SOFTENING POINT WITHIN THE LIMITS OF 140 TO 250*F., AND AN ACIDITY OF ESSENTIALLY NIL; AND RECOVERING A RESULTING PLASTICIZED RUBBERY HYDROCARBON POLYMER AS A PRODUCT OF THE PROCESS.
