A polymer having a long chain branching content peaking at greater than about 20 long chain branches per million carbon atoms, and a polydispersity index of greater than about 10 wherein the long chain branching decreases to approximately zero at the higher molecular weight portion of the molecular weight distribution. A polymer having a long chain branching content peaking at greater than about 8 long chain branches per million carbon atoms, a polydispersity index of greater than about 20 wherein the long chain branching decreases to approximately zero at the higher molecular weight portion of the molecular weight distribution. A polymer having a long chain branching content peaking at greater than about 1 long chain branches per chain, and a polydispersity index of greater than about 10 wherein the long chain branching decreases to approximately zero at the higher molecular weight portion of the molecular weight distribution.
A polymer of C2-C8 monoolefin monomers having a polydispersity index of greater than about 20 and a long chain branching content peaking at greater than about 8 long chain branches per million carbon atoms, wherein the long chain branching decreases to approximately zero at the higher molecular weight portion of the molecular weight distribution.
A method of polymerizing C2-C8monoolefin monomers comprising contacting the monomers with a chromium supported catalyst under conditions suitable for the formation of a polymer, and recovering the polymer;
