improvement of thermal properties of polypropylene and investigation of mechanical properties of cyclic copolymer/polypropylene blend

The main purpose of this article is to improve the thermal properties of polypropylene (pp) by means of cyclic copolymer (cc). pp/cc blends were produced by the melt blending process. the heat deflection temperature (hdt) of compounds was measured. heat deflection temperature of pp/50%cc compound were improved effectively. mechanical properties consisting of tensile strength, impact strength, and flexural modulus were performed. the mechanical properties of compounds increased by increasing cc proportion except impact strength resistance.
