Two separate relaxation processes were observed. Whereas the temperature of the lower temperature transition, in the vicinity of 2508C, showed a weak dependence on composition, the temperature of the upper transition, in the range 150± 508C, decreased with increasing glycerol content. The activation energy of the lower temperature transition, obtained from the dependence of the frequency of the relaxation peak upon temperature, was typical of a primary a-relaxation or glass transition process. This indicated that although glycerol was an effective plasticiser of amylose, amylose±glycerol mixtures are only partially miscible. AMYLOSE GLYCEROL PLASTICISATION Moates, G.K. Noel, T.R.
