Abstract
This invention relates to a reaction product obtained by ring-opening metathesis polymerization of norbornene ketones functionalized with the residual portion of a vinyl terminated macromonomer.
Claims20
A composition represented by the formula:
- where VTM is the residual terminal portion of a vinyl terminated macromonomer and R3 is a C1 to a C40 hydrocarbyl group, each R is, independently, H or a C1 to C40 hydrocarbyl group and R7 is a substituted or unsubstituted alkyl or substituted or unsubstituted aryl, X is C or a heteroatom, and z is 0 or 1.
A composition comprising the reaction product of:
- a C3 to a C40 vinyl or vinylene containing monomer, a ruthenium catalyst and a composition represented by the formula:
- where VTM is the residual terminal portion of a vinyl terminated macromonomer and R3 is a C1 to a C40 hydrocarbyl group, each R is, independently, H or a C1 to C40 hydrocarbyl group, R7 is a substituted or unsubstituted alkyl or substituted or unsubstituted aryl, X is C or a heteroatom, and z is 0 or 1.
