ABSTRACT:
Nodular copolymer and method of preparing a nodular copolymer by preparing a copolymer chain and coupling it with a coupling agent. The copolymers which form the nodular copolymer are formed of first and second segments, of which the second segments, containing the coupling agent, react to form the nodular region. The nodular copolymer is particularly useful as a lube oil additive.
