Patent ID: 8283428

Claim:
A polymacromonomer comprising at least one macromonomer and from 0 to 20 wt % of a C 2 to C 18 comonomer, wherein the macromonomer, prior to polymerization has: 1) from 20 to 600 carbon atoms, 2) an Mn of 280 g/mol or more, 3) an Mw of 400 g/mol or more, 4) an Mz of 600 g/mol or more, 5) an Mw/Mn of 1.5 or more, 6) vinyl termination of at least 70% (as determined by 1 H NMR) relative to total unsaturations, 7) a melting point (Tm) of 60° C. or more or an Hm of 20 J/g or less, and 8) less than 10 wt % aromatic containing monomer, based upon the weight of the macromonomer; and wherein the polymacromonomer has: a) a g value of less than 0.6, b) an Mw of greater than 30,000 g/mol, c) an Mn of greater than 20,000 g/mol, d) a branching index (g′) vis of less than 0.5, e) a melting point of 50° C. or more or an Hm of 20 J/g or less, f) less than 25% vinyl terminations (as measured by 1 H NMR) relative to total unsaturations, g) at least 70 wt % macromonomer, based upon the weight of the polymacromonomer, and h) from 0 to 20 wt % aromatic containing monomer, based upon the weight of the polymacromonomer.
