Control of functional group densities and chain flexibility are important parameters for tailoring the properties of macromolecules. The ease of synthesis of various substituted stilbene and maleimide monomers provides an enormous tool box for varying pendant group functionalities of the strictly alternating copolymers that result from radical initiated copolymerization of these comonomers. We have found, from persistence length measurements, that the steric congestion, resulting from incorporation of the stilbene units, along with the rigid cyclic anhydride or imide units in the backbone increases chain stiffness leading to a new class of semi-rigid macromolecules. Various examples of these alternating copolymers, exhibiting a wide range of properties, will be discussed.
