Abstract

SESTAVINA KATALIZATORJA IN KATALIZATORJA ZA POLIMERIZACIJO ETILENA ALI KOPOLIMERIZACIJO ETILENA Z ALFA-OLEFINOM TER POSTOPEK ZA PRIPRAVO TE SESTAVINE, oznacen s tem, da je v obliki trdnih kroglastih zrn z najmanj okoli 80% zrn z velikostjo od 30 do 40 um, s specificno povrsino od 15 do 30 m2/g in s poroznostjo od 40 do 80 vol. %, in da jo lahko definiramo s formulo (v atomskih razmerjih): Til Mg0,3-3,1 Al0,4-0, 65Cl3,2-8,2 (Et + OEt + OR')1,9-3 kjer Et pomeni etilno skupino, OEt pomeni etoksi skupino in OR' pomeni alkoksi skupino z 1 do 9 atomi ogljika v nerazvejenem ali razvejenem alkilnem delu, in v kateri je razmerje med titanom v trivalentnem stanju in vsoto titana v trivalentnem in tetravalentnem stanju v obmocju od 0,8/1 do 1/1. Postopek za pripravo sestavine katalizatorja po zahtevkih 1 do 3, oz nacen s tem, da razprisilno posusimo etanolno raztopino magnezijevega klorida, da nastane trden, zrnat, kroglast in sipek nosilec, ki vsebuje od 18 do 25 mas.% alkoholnih hidroksilov, izrazenih kot etanol, ta nosilec suspendiramo v inertni tekocini, kot n-dekanu, in ga spravimo v stik in najprej presnovimo s titanovim tetraalkoksidom Ti(OR')4, kjer R' predstavlja nerazvejeno ali razvejeno alkilno skupino, ki vsebuje od 1 do 8 atomov ogljika, pri cemer delamo pri temperaturi med sobno temperaturo in 90 C z atomskim razmerjem med magnezijem v magnezijevem kloridu in titanom v titanovem tetralkoksidu od 0,5/1 do 3/1, in nato z dietil aluminijevim kloridom ali etil aluminijevim seskvikloridom, pri cemer delamo pri temperaturi med sobno temperaturo in 80 C z razmerjem med atomi klora v dietil aluminijevem kloridu ali etil aluminijevem seskvikloridu in alkoksi skupinami, ki izvirajo iz titanovega tetraalkoksida in iz etanola, v obmocju od 0,5/1 do 1,5, da dobimo trdno sestavino katalizatorja, v kateri je razmerje med titanom v trivalentnem stanju in vsoto titana v trivalentnem in tetravalentnem stanju v obmocju od 0,8/1 do 1/1 in iz ustrezne suspenzije pridobimo trdno sestavino katalizatorja. Prijava sadrzi se 9 patentnih zahtevkov.
