At a high content of BD units in the copolymer, two crystalline modifications arise: the coiled (α) and the more straightened-out (β) form, which is analogous to PBT. The transition from the α form to the β form takes place under the action of an external force, as is evident from the appearance of the straight-line section on the load elongation curve. Nevertheless, the β form is stable under room-temperature conditions when the acting load is removed. If the BD content is relatively small, no polymorphic transitions are detected in the copolyester and only one inflection appears on the load-elongation curve. On increasing the BD content, the kinetic parameters for crystallization of the PB-ET copolymer increase: n, k, t1/2 −1. Fibre II (EG/BD=50/50) is characterized by good elasticity, dyeability, and low cost.
