NODULAR COPOLYMERS COMPRISING NARROW MWD .alpha.-OLEFIN COPOLYMERS COUPLED BY NON-CONJUGATED DIENES

摘要

NODULAR COPOLYMERS FORMED OF ALPHA-OLEFIN COPOLYMERS COUPLED BY NON-CONJUGATED DIENES 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.
