Mechanical, Thermal, And Rheological Properties of Nano-Calcium Carbonate/Polypropylene Composites Modified Bymethacrylic Acid

Polypropylene (PP)/nano-calcium carbonate (nCC) composites modified with methacrylic acid (MA) with and without dicumyl peroxide (DCP) were prepared by a twin-screw extruder. The effects of nCC and MA on the mechanical, thermal, and rheological properties of PP/nCC composites were investigated. The...
