ABSTRACT:
A method of preparing a nodular polymer by preparing a copolymer chain and coupling it to a coupling agent. The coupling agent is a non-conjugated diene. Preferably the non-conjugated diene has both double bonds Ziegler catalyst polymerizable. The preferred product comprises a norbornadiene coupled ethylene copolymer wherein the ethylene copolymer has a M.sub.z /M.sub.m of less than 2.0 and a M.sub.w /M.sub.n of less than 1.8 before coupling.
