Abstract: A method of preparing generally amorphous copolymers of ethylene and at least one norbornene (NB)-type comonomer. These polymers may be random or alternating, depending on the choice of catalyst and/or the relative ratio of the monomers used. This method comprises polymerizing said monomers in a diluent or in bulk in the presence of a cationic palladium catalyst resulting from reacting a chelating ligand with a palladium (II) compound. The catalysts employed in this invention may be represented by the formula: wherein X and Y each independently is a donor heteroatom selected from P, N, O, S and As or an organic group containing said heteroatoms, and the heteroatoms are bonded to the bridging group A; A is a divalent group selected from an organic group and phosphorus forming together with X, Y and Pd a 4, 5, 6, or 7-membered ring, and preferably a 5-membered ring; R is a hydrocarbyl group; and CA is a weakly coordinating anion.

Abstract: Addition polymers derived from norbornene-functional monomers are terminated with an olefinic moiety derived from a chain transfer agent selected from a compound having a terminal olefinic double bond between adjacent carbon atoms, excluding styrenes, vinyl ethers, and conjugated dienes and at least one of said carbon atoms has two hydrogen atoms attached thereto. The addition polymers of this invention are prepared from a single or multicomponent catalyst system including a Group VIII metal ion source. The catalyst systems are unique in that they catalyze the insertion of the chain transfer agent exclusively at a terminal end of the polymer chain.
