Photocrosslinkable copolyesters: Poly(alkylene terephthalate‐co‐1,4‐phenylene bisacrylate)

1,4‐Phenylene bis(acrylic acid) is a thermally stable diacid, which can be incorporated into polyesters. The phenylene bisacrylate structural units undergo rapid photochemical reaction in the solid state to form crosslinks. This constitutes a feasible approach to polyesters, which can be photochemically thermoset after fabrication as films and fibers. © 2000 John Wiley & Sons, Inc.
