Abstract
Novel polycyanate compositions containing one or more mesogenic moieties as lateral substituents are disclosed which provide improved processability relative to polycyanates containing one or more mesogenic moieties in the main chain of the molecule. Molecular level ordering of the resulting thermosets is maintained much similar to that found thermosets of polycyanates which have one or more mesogenic moieties in the main chain.
