Abstract
This study aims to ascertain the effect of compatibilisation on the steady shear flow properties of PP and PETP blends using two approaches: the first involved the functionalisation of PP by the addition of maleic anhydride (in situ reactive blending), and the second, the use of already-modified PP which is commercially available in Japan. The rheological properties, morphology and thermal behaviour of the compatibilised blends were studied and compared with those of uncompatibilised ones, with special consideration given to the effect of different viscosity ratios of particular blends. The influence of the molten and unmolten state of one blend component (PETP), and the effect of blend composition on rheology, was also discussed. It is concluded that the blending of PP and PETP combined with the addition of a modifier, represents an appropriate recycling method for these waste materials. 39 refs.
