Novel mixtures which comprise fusible, liquid crystalline polyesters, which have terephtalic units having lateral propargyloxy groups and a co-crosslinking agent component. The polyester is based on 2,5-bis (propargyloxy) therephtalic acid and 4,4'-dihydroxybiphenyl. These mixtures crosslink in the liquid crystalline phase at above their melting point. The novel mixtures are usable, for example, for materials having reinforcing properties.
