Ethylene → Ethylene/propylene 5-vinyl-2-norbornene 5-ethylidene-2-norbornene

Participants

Reaction Steps

In a 100-liter stainless steel polymerization reactor equipped with a stirring blade (number of stirring revolutions: 250 rpm), tetrapolymerization of ethylene, propylene, 5-vinyl-2-norbornene and 5-ethylidene-2-norbornene was continuously carried out. To the liquid phase in the reactor were fed hexane at a rate of 60 l/hr, ethylene at a rate of 3.0 kg/hr, propylene at a rate of 8.5 kg/hr, 5-vinyl-2-norbornene at a rate of 370 g/hr and 5-ethylidene-2-norbornene at a rate of 470 g/hr, and were further continuously fed hydrogen at a rate of 50N l /hr and as catalysts VOCl3 at a rate of 90 mmol/hr, Al(Et)2Cl at a rate of 420 mmol/hr and Al(Et)1.5Cl1.5 at a rate of 120 mmol/hr, through the side inlet of the reactor.
