Abstract: The present invention describes a metallocene catalyst based on a transition metal of group 4 or 5 of the periodic table, supported on a hybrid catalytic support provided with aliphatic organic groups, and a process for supporting metallocene on the hybrid catalytic support. The supported metallocene catalyst provides an ethylene polymer with broad or bimodal molecular weight distribution, in the presence of only one metallocene complex on the support.

Abstract: A method for preparing a copolymer that involves polymerizing at least one branched alkene monomer and at least one olefin monomer having a pendant benzocyclobutene (BCB) group to form a copolymer comprising a random distribution of a plurality of constitutional units corresponding to the at least one branched alkene monomer and the at least one olefin monomer. The polymerizing includes a carbocationic polymerization reaction involving sequential addition of a plurality of mixtures without terminating the carbocationic polymerization reaction, wherein the plurality of mixtures includes a mixture that includes the at least one branched alkene monomer and does not include the at least one olefin monomer having a pendant BCB group and a mixture that includes both the at least one branched alkene monomer and the at least one olefin monomer having a pendant BCB group. The copolymer composition can undergo crosslinking at elevated temperatures (preferably above 180° C.).
