High molecular weight dieneic polymers and method of producing same

Claim 1

A PROCESS FOR THE PRODUCTION OF A RESIN PRODUCT BY THERMAL TREATMENT OF POLYMERIC MATERIAL, PARTICULARLY CHARACTERIZED IN THAT MOLDABLE POLYMERIC MATERIAL OF MOLECULAR WEIGHT RANGE PREDOMINANTLY OF THE ORDER OF 1,000,000 TO 10,000,000 IS THERMALLY TREATED TO CONVERT IT INTO A RESIN THAT IS INSOLUBLE AND INFUSIBLE; SAID MOLDABLE POLYMERIC MATERIAL WITH THE AID OF A CATALYST MERIZATION OF DIENEIC MATERIAL WITH THE AID OF A CATALYST CAPABLE OF POLYMERIZING IT TO SUCH MOLECULAR WEIGHT RANGE; SAID DIENEIC MATERIAL HAVING BEEN SELECTED FROM THE GROUP CONSISTING OF BUTADIENE AND PIPERYLENE,MIXTURES OF THE FOREGOING, MIXTURES OF THE FOREGOING WITH NOT TO EXCEED AN EQUAL QUANTITY OF ISOPRENE, AND MIXTURES OF THE FOREGOING WIT HUP TO AN EQUAL QUANTITY OF MATERIAL SELECTED FROM THE GROUP CONSISTING OF STYRENE AND VINYLTOLUENE; SAID CATALYST HAVING BEEN SELECTED FROM THE GROUP CONSISTING OF THE ALKALI METAL COMPOUNDS OF ARYL, ALKYL AND ALKENYL HYDROCARBONS, MIXTURES OF THE FOREGOING, MIXTURES OF THE FOREGOING WITH ALKALI METAL ALKOXIDE; AND TURES OF THE FOREGOING WITH ALKALI METAL ALKOXIDE; AND SAID THERMAL TREATMENT BEING CONDUCTED AT TEMPERATURE BETWEEN 250*C. AND 300*C. FOR A PERIOD RANGING FROM 15 TO 50 HOURS AT 300*C. TO FROM 40 TO 400 HOURS AT 250*C.
