| titleOfInvention | Method of synthesis of ethylene copolymer with butene-1 |
| abstract | The inventive copolymerization of ethylene with butene-1 at 100-160 MPa and a maximum temperature in the reactor 513-553 K in the presence of 0-1 vol.% Hydrogen. The catalyst is the product of the sequential interaction of magnesium, 1-chlorobutane, titanium tetrachloride, triethyl or trioctylaluminium and hexene-1. After copolymerization, the pressure is reduced to 18 25 MPa and a deactivation and neutralization agent of catalyst residues, a 20-30% suspension of calcium magnesium stearate or zinc in an organic peroxide solution, is introduced. The organic peroxide is selected from the group: bis- (3,5,5-trimethyl-hexanoyl) peroxide, dioctanoyl peroxide, dipropionyl peroxide, tert-butyl peroxy-2-ethylhexanoate, tert-butyl peroxypivalate and di-tert-butyl peroxide. Peroxide is used in a solution of a mixture of n-paraffins containing 80-90 wt.% Ci3-Ci-H-napa-finins. The molar ratio of calcium, magnesium or zinc stearate to peroxide is 3-15. The content of stearate is 0.10-1.05 mol per 1 g atom of titanium and aluminum, the peroxide content is 0.02-0.15 mol per 1 r atom of titanium and aluminum. 3 tab. |
