From the temperature dependences of the amide bands (I, II, and V) in the infrared spectrum of poly (β-benzyl-L-aspartate), it was proposed that a transition of random coil-β form coexists with the usual α-ω transition. The decrease in peak absorbance at 1636 cm-1 which is characteristic of the β form and the appearance of a new band at 630 cm-1 at the usual transition temperature suggested the thermal decomposition of the β form competes with the transition.
