Liquid crystal behaviour of linear copolymers—I

摘要: Abstract A family of linear copolymers, characterized by the presence along polymer chain variable amounts two atomic groups different mesogenic potentiality, has been studied differential scanning calorimetry and X-ray diffraction methods. The range composition that allows enantiotropic mesophasic behaviour is defined for four homologous sets copolymers. experimental phase diagram gives, extrapolation, indications about potential properties extreme (corresponding to a homopolymer) shows no direct properties.
