The efficiency and randomness of the incorporation of a second monomer depend on the copolymerization parameters (see Section 3.1) and the type of chain growth method applied. For each monomer pair these factors have to be evaluated and considered for defining stmcture and functionality. In addition, basic polymer properties like solubility and thermal properties defined by the major monomer are strongly influenced by a second monomer of different functionality thus, in any random copolymerization process, it is usually not possible to introduce a second functionality without compromising the properties of the parent homopolymer, and this is enhanced with increasing the comonomer ratio. 

This chain-growth method has since been modified to polymerize a limited set of monomers, including thiophene derivatives [13], (2,5-bishexyloxy)phenylene [14], 9,9-dioctylfluorene [15], N-octylcarbazole [15b], (2,3-dihexyl)thienopyrazine [16], and N-hexylpyrrole [17]. Although each monomer has required an empirical development of the chain-growth conditions, the method has provided access to TT-conjugated polymers which, previously, were unobtainable.

The performance can be improved with the Rosenbluth chain growth method [33], where first the free nearest neighbors of the ( — l)th monomer are determined and then the new monomer is placed to one of the unoccupied sites. Since the probability for the next monomer to be set varies with the number of free neighbors, this impUes a bias given by...
