Abstract
The present invention relates to copolymers with polar and non-polar olefin blocks with a variable polar monomer content of 0.1 mol % to 99.9 mol %. The invention also relates to a method for obtaining copolymers with olefin blocks and vinyl polar monomer blocks, said method using a single-component catalytic system made up of an organometallic complex containing a metal belonging to groups VIII to X. Said organometallic complex is advantageously active in the medium without adding cocatalyst.
