Process for producing ethylene polymers and ethylene copolymers

Abstract

Abstract THE POLYMERIZATION OF ETHYLENE AND THE COPOLYMERIZATION OF ETHYLENE WITH ONE ALPHA-OLEFIN HAVING 3 TO 10 CARBON ATOMS IN THE PRESENCE OF A CATALYST PREPARED BY THE REACTION BETWEEN (A) AT LEAST ONE COMPOUND OF THE GENERAL FORMULA: R1R2HSIOAIR3R4 WHEREIN R1 AND R2 REPRESENT INDEPENDENTLY MEMBERS SELECTED FROM THE GROUP CONSISTING OF ALKYL GROUPS HAVING 1 TO 5 CARBON ATOMS, CYCLOHEXYL, PHENYL AND 1-NAPHTHYL; R3 AND R4 REPRESENT INDEPENDENTLY MEMBERS SELECTED FROM THE GROUP CONSISTING OF ALKYL GROUPS HAVING 1 TO 5 CARBON ATOMS, CYCLOBUTYL, CYCLOPENTYL, CYCLOHEXYL, PHENYL AND P-TOLYL AND (B) AT LEAST ONE COMPOUND SELECTED FROM THE GROUP CONSISTING OF (1) TIXP, XVP, TIX4-Q(OR5)Q, VOX3-R(OR5)R AND VOX3 WHEREIN X REPRESENTS HALOGEN SELCTED FROM THE GROUP CONSISTING OF CL, BR, AND I; R5 REPRESENTS ONE MEMBER SELECTED FROM THE GROUP CONSISTING OF ALKYLS HAVING 1 TO 6 CARBON ATOMS, CYCLOHEXYL, PHENYL AND P-TOLYL; P IS AN INTEGER OF 2 TO 4, Q IS AN INTEGER OF 1 TO 3; R IS AN INTEGER OF 1 TO 2; AND (2) THE SOLID COMPOUNDS ONTAINED BY THE REACTION BETWEEN ONE MEMBER SELECTED FROM THE GROUP CONSISTING OF TIX4, VX4, TIX4-Q(OR5)Q, VOX3-R(OR5)R AND VOX3 AND ONE MEMBER SELECTED FROM THE GROUP CONSISTING OF AIRV6(OR7)WX3-Y, SIR38H, (R9HSIO)S, R10R11R12SIO-(R13HSIO)T-SIR12R11R10 AND A COMBINATION OF ONE MEMBER SELECTED FROM SIR38H, (R9HSIO)S AND R10R11R12SIO-(R13HSIO)T-R12R11R10 AND ONE MEMBER SELECTED FROM ALCL3, ALBR3 AND FECL3 WHEREIN R5 AND X REPRESENT INDEPENDENTLY THE SAME GROUPS AS DEFINED ABOVE; R6 AND R7 REPRESENT INDEPENDENTLY THE SAME GROUPS AS ABOVE-DEFINED R5, R8, R9, R10, R11, R12 AND R13 REPRESENT INDEPENDENTLY THE SAME GROUPS AS ABOVEDEFINED R1 OR R2; Q AND R REPRESENT INDEPENDENTLY THE SAME INTEGERS AS ABOVE-DEFINED; V IS AN INTEGER OF 1 TO 3, W IS 0 OR AN INTEGER OF 1 TO 2, Y IS AN INTEGER OF 1 TO 3, AND V+W+Y=3; S IS AN INTEGER OF 3 TO 6; T IS AT LEAST ONE AND THE VICOSITY OF R10R11R12SIO-(R13HSIO)T-R12R11R10 IS AT MOST 2,000 ECNTISTOKES, THE MOLE RATIO OF THE COMPOUND (A) TO THE COMPOUND (B) BEING 0.5-5:1.
