A new crystal modification induced by strain was found in uniaxially oriented fibres of poly(tetramethylene succinate). This new modification (fl form) had a planar zigzag conformation of 7"1o (all trans) and a fibre identity period of 11.90.~, while the conventional ct form had a TTGTI7 conformation and fibre identity period of 10.90 A. The solid-state crystal transition between and fl forms was reversible with respect to the successive application and release of strain.
