Abstract
POSTUPAK ZA PRIPREMANJE POLIETILENA, SA PRAVIM LANCEM, MALE ILI SREDNJE GUSTINE, kopolimerizacijom etilena sa C4-C6 alfa-olefinom, naznacen time, sto se etilen kopolimerizuje sa C4-C6 alfa-olefinom, kao sa butenom-1, na povisenoj temperaturi, kao 100 do 280°C, pri povisenom pritisku, kao 1200 do 2000 bar, u trajanju od 25 do 60 sekundi, u reakcionoj fazi, u cevnom reaktoru, a u prisustvu Ciglerovog katalizatora, koji se sastoji od trialkilaluminijuma i cvrste kataliticke komponente, koja sadrzi titan, pri cemu tri-alkilaluminijum sadrzi 2 do 4 atoma ugljenika u alkil grupi, a cvrsta komponenta koja sadrzi titan dobija se: susenjem, uz rasprasivanje, etanolskog rastvora magnezijum-hlorida, kako bi se dobio supstrat od cvrstih cestica magnezijum-hlorida, koji sadrzi alkoholne hidroksile, pri cemu je bar 70 mas.% cestica velicine izmedju 0,5 do 10 µm, a sadrzaj alkoholnog hidroksila se krece od 3 do 15 mas.%, izrazeno kao etanol, reakcijom supstrata sa titan-tetrahloridom, kako bi nastao aktivirani supstrat, koji sadrzi 0,8 do 4,0 mas.% veznog titana, izrazeno kao metal, a sadrzaj alkoholnog hidroksila iznosi 0,02 do 4 mas.%, izrazeno kao etanol, i reakcijom aktiviranog supstrata sa alkilaluminijum-hloridom, sa atomskim odnosom 2:1 do 20:1 izmedju aluminjuma u alkilaluminijum-hloridu i titana u aktiviranom supstratu, pri temperaturi 0°C do 120°C, u trajanju od 100 sati do 15 minuta, kako bi titan bio hlorovan i delimicno ili potpuno redukovan titan, od cetvrorovalentnog do trovalentog stanja, pri cemu je atomski odnos izmedju aluminijuma u trialkilaluminijumu i titana u cvrstoj katalitickoj komponenti u opsegu 15:1 do 70:1. Prijava sadrzi jos 2 zavisna zahteva.
