Abstract
Polymeric compositions exhibiting superior physical properties, useful in the fabrication of composites and other applications, are prepared by the polymerization of thermotropic, monomeric materials having orderable molecular structures. The monomers comprise molecules containing mesogen groups with side chains on either end thereof terminated with reactive groups, the reactive groups being separated from the mesogens by spacer atoms. The monomers are polymerized in their crystalline or liquid crystalline state, or under conditions which assure that at least part of the monomeric molecules are in an ordered state. The reactive groups which are consequently in proximity with each other, are thereby capable of interaction without molecular diffusion, allowing substantially complete polymerizations to be achieved despite the increasing conversion and glass transition temperature of the polymers being formed.
