Novel, fusible, liquid crystalline polyesters having lateralnpropargyloxy groups which undergo self-crosslinking in the liquidncrystal phase at above their melting point are described. The polyestersnare based on 2,5-bis (propargyloxy) terephtalic acid andn4,4'-dihydroxybiphenyl. The novel fusible polyesters may be used, for example,nfor materials having reinforcing properties. |
