Abstract

Procedure to prevent the cold flow of polybutadiene, by polymerizing 1,3-butadiene with a specific stereo catalyst to obtain a polybutadiene elastomer with a high cis-1,4 content, characterized by the addition to the polymerization reaction mixture , before inactivating the halogenated olefinic hydrocarbon catalyst or a halogenated ether containing at least 2 halogen atoms in alpha position with respect to the double bond or the oxygen atom of the ether respectively containing said olefinic hydrocarbon or said ether up to 20 carbon atoms. carbon per molecule, thereby reducing the cold flow tendency of said elastomer.
