Abstract
The rheological behavior, morphologies, and tensile properties of reactively compatibilized PVDF/TPU blends are reported. Using PVDF-g-AAc as the compatibilizer, PVDF/TPU 90/10 and 10/90 blends are prepared. The carboxylic acid groups of PVDF-g-AAc react with the urethane linkages of TPU during melt blending to generate in situ PVDF-g-AAc-g-TPU which leads to compatibilization of PVDF/TPU blends. The introduction of PVDF-g-AAc into the PVDF/TPU blends causes an increase in viscosity. The rheological behavior of the compatibilized PVDF/TPU 90/10 and 10/90 blends are well described by the generalized Zener model. The addition of the compatibilizer PVDF-g-AAc reduces the dispersed-phase domain size and narrows the size distribution. ▪Author: The summary has been shortened to comply with the maximum of 700 characters.
