Abstract

The development of crystallinity in essentially amorphous polyethylene terephthalate film following immersion in a range of organic liquids at 25°C has been studied. The rate of development of crystallinity varies markedly with the liquid and although molecular size of the liquid may be a contributory factor it is not the only one. Both the equilibrium degree of crystallinity and swelling of the film vary with the liquid and in a similar manner and it would seem that polarity, type and solubility parameter of the liquid are important factors governing both equilibrium crystallinity and swelling. It is suggested that solvation of the polymer occurs and that interaction of solvated polymer and liquid leads to conditions favourable to crystallization.

    In order to have such a structure, drawing and annealing of melt-spun low oriented amorphous fibers either through an off-line process or an in-line spin-drawing process, or a direct high-speed melt spinning method is mainly utilized [2–5]. Inducing crystallization by using an organic solvent has been reported [6–10] as one of the methods for crystallization of PET at room temperature. It is known that the PET can be plasticized due to the effect of the organic solvent and the crystallization occurs at room temperature by lowering the glass transition temperature [11–14].

    On the other hand, both orientation and crystallization proceeded to form highly oriented tri-clinic crystals of PET during drawing in ethanol. It has been reported that amorphous PET immersed in strong solvents (i.e. benzene, acetone) exhibits crystallization below the glass transition temperature [5–10]. Such phenomenon is called solvent-induced crystallization.
