and ends with low isolation yields. Separating halide and acetylene groups
into two different molecules allows easier synthetic access and offers a greater
variety of monomer choices but meanwhile invites the risk of cross-linking
reactions. Control of the polycoupling conditions is thus a necessity if one in-
tends to synthesize soluble hyperbranched polymers with desired structures
and properties.
