The second step is a melt polymerization by a single pass through a wiped film reactor, in which the film of polymer melt is subjected to a high rate of shear and to a temperature in the range within which the polyester forms an anisotropic melt phase. The polyester product has an inherent viscosity of at least about 0.5 dl g.sup.-1.
