A series of poly(2-n-alkyl-l, 4-phenylene terephthalate)s with n =3 to 18 has been investigated by DSC, optical microscopy and wide-angle x-ray analysis. The degree of crystallinity as inferred from x-ray analysis is rather low but increases upon annealing. None of the materials under consideration here exhibits a glass transition. If n ≥ 12 the polyesters form nematic melts, appending of longer side chains lead to the observation of a layered mesophase.
