Structure-property relationships of polymer blends based on functionalised polyolefins

The thermal behaviour, morphology, molecular interactions and phase structure of blends based on polyolefins functionalised with diethylmaleate and commercial polymers (poly(vinyl chloride), polystyrene, poly(vinyliden fluoride)) were analysed by means of DSC, FT-IR, optical and electron microscopy. It is shown that the occurrence of partial miscibility phenomena is favoured by specific molecular interactions between the polymer components and is affected by the structure of the functionalised polyolefins, degree of functionalisation and thermal history.
