streszczenie Results of thermoplastic starch (TPS) physical properties investigations are presented. The research showed significant influence of the addition of glycerol on changes in the value of TPS glass transition temperature as well as on its mechanical properties. Higher content of glycerol content in the processed blends caused a decrease of Young modulus measured in TPS granulates. The highest storage modulus value was obtained for the blend of potato starch and 25% of glycerol, while the lowest for maize starch material mixed with the same quantity of glycerol.
