Salient features of structure of conformative-disordered crystals and liquid-crystal mesophases of a number of thermotropic polyesters

Abstract

The work covers mesophases of a number of thermotropic polyesters that have been revealed and identified for the first time. It has been possible for the first time to note the situation with the completely aromatic copolyester when a full set of physical states has been realized according to crystal - conformative-disordered mesophase - liquid crystal - melt scheme. It has been disclosed that, depending upon molecular mass, rheologic prehistory, it is possible to receive extrudates not only oriented in various ways, but the ones with various structure of lattice cell in alkene-aromatic polyesters. The allowed to reveal most promising polymers for the production of structural materials of new generationAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
