Abstract
A process for producing a butene-1 polymer is disclosed which is characterized in that, in a process for producing a homopolymer of butene-1 or a copolymer of butene-1 and .alpha.-olefin other than the butene-1 in the presence a catalyst obtained from a solid catalyst component (A), an organic aluminium compound (B) and an electron donating compound (C) and under the condition of vapor phase polymerization, the solid catalyst component (A) is a non-layer solid catalyst component obtained by producing a carrier by chlorinating at least one kind of organic magnesium compounds represented by formula MgR'R' (1) wherein R' and R', which may be the same or different, each represents an alkyl group having 1 to 20 carbon atoms, with at least one kind of chlorinating agents, the carrier produced is contacted in the presence of the electron donor with a titanic halide at a temperature of -25.degree. to +180.degree. C., and the electron donating compound (C) is a heterocyclic compound represented by ##STR1##
