Claim 1
Independent Claim
107 words
A PROCESS FOR PREPARING SOLID POLYMERS OF ALPHAOLEFINS WHICH COMPRISES ADMIXING, IN AN INERT, LIQUID REACTION MEDIUM, AN ALPHA-OLEFIN HAVING FRIM 2 TO 8 CARBON ATOMS WITH A CATALYST CONSISTING ESSENTIALLY OF ACTIVATEDF CARBON PREPARED BY THE THERMAL DECOMPOSITION OF ALUMINIM CARBIDE, AND A METAL HALIDE SELECTED FROM THE GROUP CONSISTING OF THE CHLORIDES AND FLUORIDES OF THE METALS OF GROUPS IV, VA AND VIA OF THE PERIODIC TABLE, WHEREIN THE METAL IS AT OTHER THAN ITS LOWEST VALENCE STATE, AT A TEMPERATURE OF FROM /$C. TO 250* C. AND A PRESSURE OF FROM ATMOSPHERIC TO 10,000 P.S.I.G. AND RECOVERING PREDOMINANTLY CRYSTALLINE SOLID POLYMERS OF THE ALPHA-OLEFIN.
