Method of polymerizing olefins at subatmospheric temperatures

Claim 1

A METHOD FOR PRODUCING A RUBBERY POLYMER WHICH COMPRISES FORMING A FEED MIXTURE CONSISTING OF TERTIARY MON-OLEFIN AND A DIOLEFIN, SAID MONO-OLEDIN AND DIOLEFIN HAVING FORM 4 TO 8 CARBON ATOMS IN THE MOLECULE, CHILLING SAID FEED MIXTURE OF A TEMPERATURE IN THE RANGE BETWEEN -120* AND -175* F., FORMING A CATALYTIC SOLUTION OF A FRIEDEL-CRAFTS CATALYST IN A SOLVENT THEREFOR WHICH DOES NOT FORM COMPLEXES THEREWITH AND IS UNREACTIVE WITH SAID MONO-OLEFIN AND DIOLEFIN, CHILLING SAID SOLUTION TO A TEMPERATURE IN THE RANGE BETWEEN -120* AND -175* F., MAINTAINING SAID FEED MIXTURE AND SAID CATALYST SOLUTION AT A SUPERATMOSPHERIC PRESSURE, ADMIXING SAID CHILLED FEED MIXTURE WITH AN AMOUNT OF CATALYST SOLUTION IN THE RANGE BETWEEN 0.025 AND 0.10 VOLUME PER VOLUME OF FEED AT A PRESSURE NO GREATER THAN 1 POUND PER SQUARE INCH ABSOLUTE AND AT A TEMPERATURE IN THE RANGE BETWEEN - 120* AND -175* F. TO CAUSE SUBSTANTIAL POLYMERIZATION OF SAID FEED MIXTURE TO FORM A PRODUCT AND SUBSTANTIAL VAPORIZATION OF UNREACTED HYDROCARBONS, REMOVING HEAT OF SAID POLYMERIZATION REACTION BY THE LATENT HEAT OF VAPORIZATION OF SAID UNREATED HYDROCARBONS, AND RECOVERING SAID PRODUCT.

Claim 2

A METHOD FOR PRODUCING A RUBBERY POLYMER WHICH COMPRISES FORMING A FEED MIXTURE CONSISTING OF TERTIARY MON-OLEFIN AND A DIOLEFIN, SAID MONO-OLEDIN AND DIOLEFIN HAVING FORM 4 TO 8 CARBON ATOMS IN THE MOLECULE, CHILLING SAID FEED MIXTURE OF A TEMPERATURE IN THE RANGE BETWEEN -120* AND -175* F., FORMING A CATALYTIC SOLUTION OF A FRIEDEL-CRAFTS CATALYST IN A SOLVENT THEREFOR WHICH DOES NOT FORM COMPLEXES THEREWITH AND IS UNREACTIVE WITH SAID MONO-OLEFIN AND DIOLEFIN, CHILLING SAID SOLUTION TO A TEMPERATURE IN THE RANGE BETWEEN -120* AND -175* F., MAINTAINING SAID FEED MIXTURE AND SAID CATALYST SOLUTION AT A SUPERATMOSPHERIC PRESSURE, ADMIXING SAID CHILLED FEED MIXTURE WITH AN AMOUNT OF CATALYST SOLUTION IN THE RANGE BETWEEN 0.025 AND 0.10 VOLUME PER VOLUME OF FEED AT A PRESSURE NO GREATER THAN 1 POUND PER SQUARE INCH ABSOLUTE AND AT A TEMPERATURE IN THE RANGE BETWEEN - 120* AND -175* F. TO CAUSE SUBSTANTIAL POLYMERIZATION OF SAID FEED MIXTURE TO FORM A PRODUCT AND SUBSTANTIAL VAPORIZATION OF UNREACTED HYDROCARBONS, REMOVING HEAT OF SAID POLYMERIZATION REACTION BY THE LATENT HEAT OF VAPORIZATION OF SAID UNREATED HYDROCARBONS, AND RECOVERING SAID PRODUCT.
