Abstract:
1. A process comprising polymerizing, in the presence of a Group 8-10 metal complex and an activator, one of the monomer groups (a) through (f): (a) a vinyl monomer selected from the group consisting of vinyl aromatics, vinyl ethers, vinyl esters, and vinyl halides thereof; (b) a vinyl monomer selected from the group consisting of vinyl ethers, vinyl esters, and vinyl halides, and at least one olefin; (c) a hydroxy-functional monomer selected from the group consisting of hydroxyalkyl acrylates, hydroxyalkyl methacrylates, allylic alcohols, and alkoxylated allylic alcohols, and at least one alkyl or aryl acrylate or at least one alkyl or aryl methacrylate; (d) a hydroxy-functional monomer selected from the group consisting of hydroxyalkyl acrylates, hydroxyalkyl methacrylates, allylic alcohols, and alkoxylated allylic alcohols, at least one alkyl or aryl acrylate or at least one alkyl or aryl methacrylate, and at least one olefin; (e) a hydroxy-functional monomer selected from the group consisting of hydroxyalkyl acrylates, hydroxyalkyl methacrylates, allylic alcohols, and alkoxylated allylic alcohols, and at least one vinyl aromatic monomer; or (f) a hydroxy-functional monomer selected from the group consisting of hydroxyalkyl acrylates, hydroxyalkyl methacrylates, allylic alcohols, and alkoxylated allylic alcohols, at least one vinyl aromatic monomer, and at least one olefin; wherein the complex has the general structure: wherein M is a Group 8-10 metal; L is a polymerization-stable ligand selected from isoindolines or bis(imines); X is a labile ligand; and n is greater than or equal to 1; and wherein L is an isoindoline ligand having the general structure: wherein A and A′ are the same or different aryl or heteraryl groups.
