PROCEDIMIENTO PARA LA PRODUCCION DE POLIMEROS DE ALQUENOS C{SUB,2} IA DE UN SISTEMA CATALIZADOR, AÑADIENDOSE UN COMPUESTO DE FORMULA GENERAL I: EN DONDE M{SUP,1} SIGNIFICA BORO, ALUMINIO, GALIO, INDIO O TALIO Y R{SUP,1}, R{SUP,2} CORRESPONDEN A HIDROGENO, ALQUILO C{SUB,1} C{SUB,10}, ARILO C{SUB,6} UILARILO O ARILOALQUILO EN CADA CASO CON 1 HASTA 10 ATOMOS EN EL RADICAL ALQUILO Y CON 6 HASTA 20 ATOMOS DE C EN EL RADICAL ARILO, UN CICLOALQUILO DE 5 HASTA 7 MIEMBROS, QUE PUEDE PORTAR, POR SU PARTE, COMO SUSTITUYENTE UN ALQUILO C{SUB,1} ,10}, O SIENDO R{SUP,1} Y R{SUP,2} JUNTOS GRUPOS CICLICOS CON 4 A 15 ATOMOS DE C. A process for the production of polymers of 2-12C alkenes at -50 to 300 degrees C and 0.5-3000 bar in presence of a catalyst system, with the addition of a compound of formula H-M<1)<R )R (I); where M = B, Al, Ga, In or Tl; R , R = H, 1-10C alkyl, 6-15C aryl, or alkaryl or aralkyl with a 1-10C alkyl and a 6-20C aryl group, or 5- to 7-membered cycloalkyl (optionally substituted with 1-10C alkyl); or R + R may form a 4-15C cyclic group. Preferably R and R together form part of a 4-15C bicyclic group; M = boron. The catalyst system contains (A) a metallocene complex and (B) a metallocenium ion-forming compound. A metal compound of formula M<4)<R )r(R )s(R )t (IV) may also be added; M = alkali or alkaline earth metal, or a Sub-Group III metal, i.e. B, Al, Ga, In or Tl; R = 1-10C alkyl, 6-15C aryl, or alkaryl or aralkyl with 1-10C alkyl and 6-20C aryl groups; R , R = as for R , or also halogen or 1-10C alkoxy; r = 1-3; s, t = 0-2; r + s + t = the valency of M .
