A polymerization process for preparing a polymer, comprising contacting at least one acyclic aliphatic olefin monomer and a catalyst composition comprising a palladium metal center complexed with at least one ligand, wherein the at least one ligand has a structure according to Formula I
wherein R1-R14 are independently selected from a hydrogen; a halogen; and, a substituent selected from C1-C20 alkyl, C3-C20 cycloalkyl, C2-C20 alkenyl, C2-C20 alkynyl, aryl, arylalkyl, alkylaryl, phenyl, biphenyl, C1-C20 carboxylate, C1-C20 alkoxy, C2-C20 alkenyloxy, C2-C20 alkynyloxy, aryloxy, C2-C20 alkoxycarbonyl, C1-C20 alkylthio, C1-C20 alkylsulfonyl, C1-C20 alkylsulfinyl, silyl and derivatives thereof;
wherein Q is selected from phosphorus and arsenic;
wherein R15 is selected from -SO3, -PO3, -AsO3, and -C(CF3)2O;
wherein the polymer prepared exhibits a branch content of ≤ 15 branched/1,000 carbon atoms, wherein the branch content is determined by Carbon 13 NMR and the melting point of the polymer prepared;
with the proviso that R1-R10 are not all hydrogen;
with the proviso that when R2, R4, R7 and R9 are each a hydrogen, none of R1, R5, R6 and R10 are CH3, CF3, F, SMe2, biphenyl or phenoxy; and,
with the proviso that when R15 is -SO3, -PO3, or -AsO3, none of R1, R5, R6 and R10 is a polar group.
