Block polymer preparation |
| abstract |
Branched block copolymers are prepared by polymerizing a conjugated diene with or without a monovinyl substituted aromatic compound employing an organoalkalimetal initiator, coupling after substantially complete conversion with a reagent having at least two groups capable of combining with the polymer alkali metal moieties without terminating activity thereof, and thereafter adding a polymerizable monomer other than that employed in the first step. |
