The structure of thermoplastic polyurethane elastomers is affected by synthesis conditions as well as by processing conditions. In the batch-wise production of TPU granules, quality deviations often occur from one production to another, which consequently influence the structure of the material and the end use quality of manufactured products. On the other hand, it is possible to produce TPU with specific properties by varying the synthesis and process conditions. Differential scanning calorimetry (DSC) was used to investigate Structural differences in two TPUs. DSC can reveal the melting behaviour and residual crystallinity after processing which can depend on the stoichiometry and processing conditions. (C) 2003 Elsevier Ltd. All rights reserved.
