Abstract
A solid product as a catalyst component for an olefin polymerization catalyst is obtained by the reaction of metallic magnesium, an alcohol, and a halogen in an amount ranging from 0.019 to 0.06 gram-atom per one mole of metallic magnesium. Alternatively, the halogen component is a halogen-containing compound which contains not less than 0.0001 gram-atom of a halogen atom per one gram-atom of metallic magnesium.
