Polyethylene, having a good workability, was manufd. using catalyst obtained from reaction of compn. [A [B [C .[A is hydrocarbon-insol. Product from the reaction of organoaluminum compd. (R4AlX2, R4 = C1-8 hydrocarbon, X = halogen) and hydrocarbon-sol. product from the reaction of organoaluminum compd. (R1aR2bAl(OR3)3-(a+b), R1,R2,R3 = C1-8 hydrocarbon, a+b = 2.20-2.85) and compd. contd. 1 Ti atom and 3 halogen. [B is organoaluminum compd. (R5cR6dAl(OR7)3-(c+d), R5,R6,R7 = C1-8 hydrocarbon, c+d = 1.5-2.0) or organosiloxyaluminum compd. (R8eR9fAl(OR10)g(OSiR11R12R13)h,R8,R9,R10 = C1-8 hydrocarbon, R11R12R13 = C1-8 hydrocar- ! bon or H, e+f+g+h = 3.0, e+f = 1.5-2.0.)
