Mesomorphic structures and order-disorder transitions in comb copolymer-like systems obtained by hydrogen bonding of noncharged or charged homopolymers with amphiphiles are discussed. The amphiphiles consist of attractive and repulsive moieties and the emphasis will be on the situation without an additional solvent phase. Poly(4-vinyl pyridine), i.e. P4VP, hydrogen bonded to stoichiometric amounts of pentadecylphenol (PDP) is one of the characteristic examples. Small angle X-ray scattering and dynamic rheology demonstrate that this system forms a disordered melt at temperatures above the order-disorder temperature (T(ODT)), whereas for T1.0 which is further hydrogen bonded to PDP. The presented results offer guidelines to apply the concepts to other polymers as well, with an example mentioned in relation to polyamide 6. Copyright (C) 1999 Elsevier Science B.V.
