Abstract

A polymer having alkali metal atoms attached thereto or a polymer-hydrocarbyl alkali metal compound mixture is treated to increase molecular weight by reaction with an organic halogen compound and an ether as a Lewis base. In the examples, a polymer obtained by homopolymerizing butadiene or copolymerizing butadiene with styrene in the presence of n-butyl lithium is treated prior to deactivation with s-C 4 H 9 Cl or s-C 8 H 17 Br/(C 2 H 5 ) 2 O, tetrahydrofuran or dioxan, and a polybutadiene obtained by Ziegler polymerization and deactivation is lithiated with n-butyl lithium and treated with 2-bromopentane (C 4 H 9 ) 2 O.
