Abstract
Comb copolymers with polyacrylamide or poly-methacarylamide main chains and lipopeptidic side chains were synthesized in two steps: synthesis of a polymerizable lipopeptide followed by radical polymerization of the lipopeptidic macromonomer. X ray diffraction and DSC studies showed that comb copolymers exhibit both a thermotropic and a lyotropic behaviour. The influence of the nature and the degree of polymerization of the peptidic chains on the type (smectic, nematic or cholesteric) and the domain of stability of the liquid-crystalline structures was established. In the case of smectic structures, the influence of the solvent concentration and the degree of polymerization of the peptidic chains on the distances between the smectic planes was also established.Keywords
