Processing-improved properties and morphology of PP/COC blends
Original language description
The aim of this study was to improve mechanical properties of polypropylene/cycloolefin copolymer (PP/COC) blends by processing-induced formation of long COC fibers. We focused our attention on finding processing conditions yielding PP/COC fibrous morphology in a well-defined, reproducible way. A number of PP/COC blends were prepared by both compression molding and injection molding (IM). Neat polymers were characterized by rheological measurements, whereas phase morphology of the resulting blends was characterized by means of scanning electron microscopy. The longest COC fibers were achieved in the injection molded PP/COC blends with compositions 75/25 and 70/30 wt %. Elastic modulus and yield strength were measured as functions of the blend composition using an Instron tensile tester; statistically significant improvement of the yield strength due to fibrous morphology was proved.
