The synthesis of bisacid A2 in a high state of purity, the preparation of unsaturated copolyesters therefrom, the preparation of solutions of the latter in suitable monomers, followed by casting of those solutions after addition of catalysts and curing of the material to obtain crosslinked polyester sheet, has been described in earlier communications. 1–3 This paper deals with the heat distortion temperatures 4 and the (modified) Vicat softening points 5 of the cast sheets of various copolyesters at various monomer contents.
