Crosslinkable liquid crystalline co-polyesters based on substituted terephthalic acid moiety have been synthesised and their phase behaviour characterised. The network formation by thermally activated radical reaction has been examined on polymers with different amounts of monomer units bearing reactive acryloyloxy substituents at the terephthalic group. The relatively low melting temperatures allow fibre extrusion to be performed from a polymer matrix containing the crosslink reaction activator. Successive thermal curing produces a stabilisation of the macroscopic orientation of the liquid crystalline network.
