Abstract:
The uniaxial deformation and recovery of primarily amorphous poly(butylene terephthalate) [24968-12-5] was investigated by simultaneous FTIR spectroscopy and stress-strain measurements. Contrary to annealed cryst. samples, the stress-induced transformation of the polymer chains to a conformation deviating slightly from the planar all-trans cryst. b-form was almost irreversible.
