Compatibilization Effect of Polyfunctional Monomers on PP/TPU Blends
This paper mainly researched how polyfunctional monomers affect the Compatibilization of PP/TPU blends. With triallylisocyanurate (TAIC) and trimethylolpropane triacrylate (TMPTA) which belong to polyfunctional monomers as compatibilizers, various PP/TPU blends were prepared via melt mixing by using a twin-screw extruder. It is investigated that the effect of polyfunctional monomer on the mechanical properties, morphology and melt flowing behavior of the blends. The results show that the compatibility of PP/TPU is improved by adding moderate TAIC or TMPTA, and the compatibilization effect of TMPTA is superior to TAIC, especially when the content of monomers is 3 phr.
