Patent ID: 7985815

Claim:
A process for preparing a polymer comprising reacting a first monomer with a second monomer, which may be the same or different from the first monomer, in the presence of a metal co-ordination complex catalyst and under conditions so as to polymerize the monomers to form a polymer comprising: a first repeat unit comprising Ar h substituted with at least two X and optionally at least one additional substituent, wherein Ar h comprises a triazine group, and each X is the same or different and independently comprises a halide, cyano, an alkyl group, an alkoxy group, a substituted aryl group, a substituted heteroaryl group, an unsubstituted aryl group, or an unsubstituted heteroaryl group; and, a second repeat unit that is adjacent to the first repeat unit, wherein each X that is part of a main body of the polymer backbone is directly conjugated to the second repeat unit.
