A process for preparing a copolymer including one or more phosphorus-containing mer units, the process comprising:
- anionically polymerizing conjugated diene monomer, vinyl organophosphine monomer, and optionally monomer copolymerizable therewith.
A copolymer having one or more phosphorus-containing mer units defined by the formula V:
- where R1 and R2 are each independently monovalent organic groups, or where R1 and R2 join to form a divalent organic group, and where R3, R4, and R5 are each independently hydrogen or monovalent organic groups, or where R3 and R4 join to form a divalent organic group.
