| abstract |
Linear, melt processable, crosslinkable, thermotropic wholly aromatic ("liquid crystal") polyesters are prepared by polymerizing difunctional stilbene or tolan derivatives as comonomers with non-ethylenically and non-acetylenically unsaturated aromatic diols, dicarboxylic acids, hydroxy acids or reactive derivatives thereof. Shaped structures made from these polyesters are crosslinked using electron-poor monomers, such as maleic anhydride. |
