| titleOfInvention | PROCESS FOR PREPARING HIGHLY STEREO REGULAR POLYMERS OR COPOLYMERS OF .alpha.-OLEFINS CONTAINING AT LEAST THREE CARBON ATOMS, AND CATALYSTS USED THEREFOR |
| abstract | ABSTRACT OF THE DISCLOSURE Highly stereoregular polymers or copolymers of .alpha.-olefins containing at least 3 carbon atoms are prepared in high yields by poly-merizing or copolymerizing the .alpha.-olefins in the presence of a catalyst composed of (a) an improved solid transition metal catalyst component prepared by reacting (1) a magnesium-containing reaction product derived from a member of the group consisting of (i) a magnesium halide, (ii) an active hydrogen-containing compound, (iii) an organic acid ester and (iv) a silicon or tin compound containing at least one halogen atom or hydrocarbon group bonded directly to silicon or tin with (2) (a) titanium compound, and (b) an organometallic compound of a metal selected from aluminum, magnesium and zinc. The novel catalyst affords polymers and copolymers of .alpha.-olefins with at least 3 carbon atoms having more improved stereoregularity in high yields, and can be prepared without the need for the time-consuming mixing-pulverizing means. |
