The radical catalyzed homopolymerization of the furan-maleic anhydride (F-MAH) Diels-Alder adduct yields a saturated homopoly-mer at temperatures below 60 C, and an unsaturated equimolar alternating copolymer at elevated temperatures, due to retrograde dissociation of the adduct (10, 11). The copolymerization of monomeric furan and maleic anhydride yields the same unsaturated alternating copolymer, independent of temperature (1C)).

Similarly, the two structural units of poly[ 8-[(4 -(2/ ,35)-2-fluoro-3-methyl-pentyloxycarbonyl)-3 -fluorophenyl-4"-phenoxy)octyl]vinyl ether)-co- 11-[(4 -(2/ ,3S)-2-fluoro-3-methylpentyloxycarbo-nyl)-3 -fluorophenyl-4"-phenox.y)unde-cyl]vinyl ether are isomorphic within both the SmC and SmA mesophases, but not the more ordered phases (Fig. 24 b) [139]. Therefore, copolymerization can be used to eliminate the crystalline and/or more ordered smectic phases of the corresponding homopoly mer(s).

The addition reaction of 2 mol of sec-butyllithium with 1,3-bis(l-phenylethenyl)benzene (eqn [7]) proceeds rapidly and efBdently to produce the corresponding dUithium species that is soluble in toluene or in cydohexane. Although this dUithium initiator is useful for the preparation of homopoly-mers and triblock copolymers with relatively narrow molecular weight distributions, it is necessary to add a smaU amormt of Lewis base or two or more equivalents of lithium alkoxide (e.g., lithium sec-butoxide) to produce narrow, monomodal molecular weight distributions.

This tabulation is limited to reports of measurements on solutions that contain only one nonelectrolyte homopoly-mer solutions with a copolymer, polyelectrolyte, or polymer mixture have been excluded. Solvents for the solutions in this compilation are liquids comprising single molecular entities i.e., references to studies in which the solvent is a binary or ternary mixture or a mixture of oligomers are not included. 

We have been discussing the mechanism of polymerization of a single monomer (homopolymer). However, when two or more monomers polymerize in situ, the chains obtained differ in composition and location of each mer. These are controlled by the ratios between the tendency to homopoly-merize and to cross-polymerize ti and rj. (Details will follow.)...
