Homopolymers or copolymers of acrylates, homopolymers or copolymers of norbornenes, and copolymers of acrylates with norbornenes, may be prepared by contacting acrylate and/or norbornene monomer reactant under polymerization conditions and in the presence of a solvent with a catalyst system consisting essentially of a Pd(II) dimer component having the formula: [(L)Pd(R)(X)].sub.2, where L is a monodentate phosphorus or nitrogen ligand, X is an anionic group, and R is an alkyl or aryl group.

Гомополимеры или сополимеры акрилитов, гомополимеров или сополимеров norbornenes, и сополимеров акрилитов с norbornenes, могут быть подготовлены путем контактировать реактант акрилита and/or мономера norbornene под условиями полимерности и in the presence of растворитель при система катализатора состоя необходимо компонента димера Pd(II) имея формулу: [ (L)Pd(R)(X)].sub.2, где л будет ligand фосфора или азота monodentate, х будет анионной группой, и р будет алкиловая или ариловая группа.
