Abstract

The lattice parameters of film-grade poly(phenylene sulphide), PPS, have been studied at room temperature as a function of thermal history. Effects of crystallization temperature and annealing time for films crystallized from the rubbery amorphous state were investigated using wide- and small-angle X-ray diffraction, bulk density and thermal analysis techniques. The dimensions of the crystal lattice are found to depend upon prior thermal treatment conditions. As the cold crystallization temperature, Tc, increases, or the annealing time at fixed temperature increases, the bulk density, degree of crystallinity, and crystal perfection increase. With an increase in annealing time at fixed temperature, lattice a, b, and c decrease leading to an increase in lattice density. As the cold crystallization temperature increases, lattice density also increases as a result of a systematic decrease in lattice parameters a and b.
