    • A process for producing polyethylene comprising polymerizing ethylene in a medium of a hydrocarbon solvent at a temperature within the range of from 30.degree. to 110.degree. C. under a pressure of from 1 to 60 atm.g. in the presence of a complex organometallic catalyst; said catalyst consisting of an alkylaluminiumhalide of the formula AlR.sub.n (X).sub.3-n (I), wherein R is an alkyl with a number of carbon atoms from 2 to 18; X is Cl, Br, I; n=1 or 2; an oxyvanadiumalkoxide of the formula OV(OR').sub.3 (II), wherein R' is an alkyl with a number of carbon atoms from 2 to 20; and a complex of acrylonitrile with diethylaluminiumchloride of the formula CH.sub.2 =CHCN.Al(C.sub.2 H.sub.5).sub.2 Cl (III); molar ratio between said catalytic components I:II:III being equal to 5-20:1:1-5, respectively. The process makes it possible to obtain polyethylene with a wide (5 to 10) molecular-mass distribution and with an enhanced adhesion to a metal (more than 3000 g/cm). Polyethylene possessing the above-cited characteristics is readily processed by the extrusion method to articles of household and industrial applications.
    • 一种生产聚乙烯的方法,包括在烃溶剂的介质中,在30至110℃的温度范围内,在1至60大气压的压力下聚合乙烯。 在复合有机金属催化剂存在下; 所述催化剂由式AlRn(X)3-n(I)的烷基铝卤化物组成,其中R是碳原子数为2至18的烷基; X是Cl,Br,I; n = 1或2; 式(OR')3(II)的氧钒烷氧化物,其中R'是碳原子数为2至20的烷基; 和丙烯腈与式CH 2 = CHCN.Al(C 2 H 5)2 Cl(III)的二乙基氯化铝的络合物; 所述催化组分I:II:III之间的摩尔比分别等于5-20:1:1-5。 该方法可以获得具有宽(5至10)分子质量分布并且对金属(大于3000g / cm 3)的增强的粘附性的聚乙烯。 具有上述特征的聚乙烯通过挤出法容易地加工成家用和工业用途。
