Abstract
The invention relates to a family of Pd(II)-based catalysts of general formula (I) reproduced below for use in the production of olefin/polar vinyl monomer copolymers and olefin homopolymers. The invention also refers to ligands that are intermediates in the synthesis of the catalysts, to the process for the synthesis of homo- and copolymers using these catalysts, and to the homo- and copolymers thus obtained.
Claims8
