Abstract:
1. A process for preparing a multifunctional composition, the process comprising a step of: contacting together ingredients comprising: a multifunctional chain shuttling agent comprising a compound having one or more moieties capable of chain shuttling, one or more moieties capable of protecting or polymerization initiating, and at least one polyvalent linking group; the chain shuttling moieties being different than the protecting/polymerization initiating moieties, each chain shuttling moiety and polymerization initiating moiety independently comprising a metal cation, each metal of the metal cations independently being tin or a metal of any one of Groups 2, 12, and 13 of the Periodic Table of the Elements; each polyvalent linking group independently comprising from 2 to 20 carbon atoms; 0, 1, or 2 carbon-carbon double bonds; and from 1 to 4 heteroatoms, each heteroatom independently being either an oxygen atom, sulfur atom, hydrogen-substituted nitrogen atom, hydrocarbyl-substituted nitrogen atom, hydrogen-substituted phosphorous atom, or hydrocarbyl-substituted phosphorous atom; each metal cation of a chain shuttling moiety independently being bonded to a different carbon atom of the same polyvalent linking group or to a carbon atom of a different polyvalent linking group and each metal cation of a polymerization initiating moiety independently being bonded to a different heteroatom of the same polyvalent linking group or to a heteroatom of a different polyvalent linking group, the metal cations thereby being spaced apart from each other by at least one polyvalent linking group; an original olefin polymerization catalyst; and, an original cocatalyst, the contacting being performed under catalyst preparing conditions, thereby preparing the multifunctional composition, the multifunctional composition being capable of functioning as a multifunctional chain shuttling agent and an olefin polymerization catalyst.
