Patent ID: 7511105

Claim:
A process for forming a long chain branching polymer having the formula: where each R is independently H or a C 1 -C 30 substituted or unsubstituted, linear, branched, or cyclic alkyl or aryl moiety, n is an integer between 500 and 100,000, inclusive, m is an integer between 100 and 50,000, inclusive, Xâ€² is a residue of a moiety X, where X is a terminal vinyl or norbornene group reactive under polymerization conditions, Y is a chain transfer agent, Yâ€² is a residue of Y, R 1 is a C 1 to C 10 substituted or unsubstituted, linear, branched, or cyclic alkyl or aryl, q is an integer in the range from 1-500, inclusive, and p is an integer in the range from 0-1,000, inclusive, comprising: providing an alpha-olefin monomer; providing a â€œTâ€ reagent having the formula: where X is a moiety having a terminal vinyl or norbornene group reactive under polymerization conditions, R 1 is C 1 to C 10 substituted or unsubstituted, linear, branched, or cyclic alkyl or aryl, and Y is a chain transfer agent; providing a metallocene catalyst; mixing the olefin monomer, the â€œTâ€ reagent, and the catalyst in a container to yield a reaction mixture; and allowing the reaction mixture to react under polymerization conditions for a period of time sufficient to form a long chain branching polymer.
