Abstract

<abstract abstract-type="main"> <title> <x xml:space="preserve">Abstract</x> </title> <p>In this study, polypropylene/ethylene–octene copolymer (PP/POE) blends, PP/talc, and PP/POE/micro‐talc (MT) composites were fabricated using a twin screw. To estimate the performances of the PP/POE blends, PP/talc, and PP/POE/MT composites, mechanical properties, heat deflection temperature (<italic>HDT</italic>), thermomechanical analysis, and isothermal crystallization characterization were conducted. Incorporating talc particles increased the tensile strength, flexural properties, and <italic>HDT</italic> of the PP matrix, but reduced the elongation at break and notched impact strength. The inclusion of POE elastomers in the PP matrix yielded the opposite effect on PP/talc composites. PP/POE/MT composites provide a compromise that improves both the flexural properties and notched impact strength. Moreover, the inclusion of talc particles in PP/POE blends induced heterogeneous nucleation and considerably reduced the crystallization time. Consequently, the time required for processing was also greatly reduced. POLYM. COMPOS., 36:69–77, 2015. © 2014 Society of Plastics Engineers</p> </abstract>
