摘要:
A fine solid titanium trichloride is used as a catalyst for a polymerization of an .alpha.-olefin. The solid titanium trichloride is produced by precipitating it at lower than 150.degree. C. from a liquid titanium trichloride complex in the presence of an ester having the formula ##STR1## wherein R.sup.1 and R.sup.2 respectively represent a hydrocarbon moiety and total carbon atoms of R.sup.1 and R.sup.2 are 10 or more.
