Abstract
En prokatalysatorblanding til poly- merisering av alfaalkener er beskrevet. Prokatalysatoren fremstilles i trinn og omfatter en bærer basert på minst ett ¿ uorganisk oksid som har få eller ingen hydroksylgrupper på sin overflate. Bæreren omsettes med en magnesium- forbindelse og en eller flere overgangs- metallforbindelser valgt fra gruppe IVB og VB i det periodiske system. Det er funnet at en slik katalysator har de beste egenskaper når: a) bæreren impregneres med en blanding av Mg-forbindelsen.og en eller flere forbindelser av et overgangsmetall fra gruppe IVB eller VB i 4et periodiske system, som leser opp Mg-forbindelsen, og b) klorering med en forbindelse som ikke inneholder titan slik at 1) bæreren først behandles med en blanding i form av en opp- ; . løsning av Mg-forbindelsen og over- gangsmetallforbindelsen og det produkt som således fås kloreres, eller 2) bæreren først kloreres og deretter behandles med den ovenfor angitte blandingenen l form av en oppløsning, eller 3) Mg-forbindelsen og overgangsmetall- ^forbindelsen impregneres inn i bæreren uten at der foretas noen separat opplesning og det produkt som således fås kloreres.A procatalyst composition for polymerization of alpha alkenes is disclosed. The procatalyst is prepared in steps and comprises a carrier based on at least one inorganic oxide having little or no hydroxyl groups on its surface. The carrier is reacted with a magnesium compound and one or more transition metal compounds selected from group IVB and VB in the periodic table. It has been found that such a catalyst has the best properties when: a) the carrier is impregnated with a mixture of the Mg compound and one or more compounds of a transition metal from Group IVB or VB in the periodic system which reads the Mg compound; and b) chlorination with a non-titanium compound such that 1) the carrier is first treated with a mixture in the form of a compound; . solution of the Mg compound and the transition metal compound and the product thus obtained is chlorinated, or 2) the carrier is first chlorinated and then treated with the above mixture in the form of a solution, or 3) the Mg compound and the transition metal compound are impregnated in the carrier without any separate readings being made and the product thus obtained is chlorinated.
