Abstract: Embodiments of this disclosure include polymers comprising the polymerized product of ethylene, at least one diene comonomer, and optionally at least one C3 to C14 comonomer. The polymer comprises tri -functional long-chain branches resulting from the diene that occur at a frequency of at least 0.03 per 1000 carbon atoms of the polymer. The diene has a structure according to formula (I):

Abstract: Processes of synthesizing long-chain branched polymers. The processes include contacting together one or more C2-C14 alkene monomers, at least one diene, optionally a solvent, and a multi-chain catalyst optionally in the presence of hydrogen, wherein the multi-chain catalyst comprises a plurality of polymerization sites; producing at least two polymer chains of the C2-C14 alkene monomers, each polymer chain polymerizing at one of the polymerization sites; synthesizing the long-chain branched polymers by connecting the two polymer chains with the diene, the joining of the two polymer chains being performed in a concerted manner during the polymerization; and producing tri-functional long chain branches from the diene, wherein the tri-functional long chain branches occur at a frequency of at least 0.03 per 1000 carbon atoms. The diene has a structure according to formula (I):

The diene has a structure according to formula (I):
