Abstract:
1. A process for the polymerization and co-polymerization of olefinic monomers employing a polymer-bound chain transfer catalyst to produce a molecular weight-controlled macronomer, said process comprising: (i) forming a polymerization medium comprising said olefinic monomers and said chain transfer catalyst, and optionally solvent(s), and (ii) polymerizing said olefinic monomers; (iii) effecting a phase partition of the chain transfer catalyst; and (iv) separating said chain transfer catalyst from said macromonomer, wherein said chain transfer catalyst is represented by a central moiety CAT and one or more substituents Poly positioned on CAT to form wherein said Poly radicals are linear or branched polymers with an average chain length equal to or greater than 20 atoms; wherein x is an integer greater than or equal to 1; wherein CAT comprises a metal atom coordinated to one or more ligands; and wherein said moiety CAT is defined such that the compound CAT-(R
