Abstract:V razvoju novih polimernih materialov zavzemajo pomembno mesto polimerni kompoziti, proizvedeni iz polipropilena (PP). Preučevali smo kompozite iz PP in talka, površinsko obdelanega z aminosilani, in polimernega modifikatorja. Kompoziti so vsebovali 12 vol.% obdelanega talka in do 10 vol.% blokkpolimerov poli-(stiren-b-etilen-co-butilen-b-stirena)(SEBS) različnih molskih mas, SEBS, grafitiranega z maleinanhidridom (SEBS-gMA), ali PP, grafitiranega z maleinanhidridom (PP-gMA). Vzorce smo pripravili preko taline v Brabenderjevem gnetilniku in s stiskanjem v plošče na laboratorijski stiskalnici. Kompozite PP/talk/SEBS-gMA in PP/talk/PP-gMA smo pripravili tudi pri različnih časih gnetenja. V delu so komentirani rezultati meritev predelovalnih lastnosti (torzijski moment mešanja), mehanskih lastnosti (natezne lastnosti, zarezna udarna žilavost) in študija morfologije v odvisnosti od sestave in tehnoloških pogojev priprave kompozitov.

Title:Investigations of modified polypropylene and talc composites
Abstract:Polymer composites based on polypropylene (PP) play an important role in the development of new polymeric materials. Composites of PP, surface treated talc and polymer modifier were investigated. The composites contained 12 vol.% of treated talc and up to 10 vol.% of poly(styrene-b-ethylene-co-butylene-b-styrene) block copolymers (SEBS) of different molecular weights, SEBS grafted with maleic anhydride (SEB-gMA) or PP grafted with maleic anhydride (PP-gMA). Samples were prepared by melt-mixing in a Brabender kneading chamber and were compression molded into plates on a laboratory press. PP/talc/SEBS-gMA and PP/talc/PP-gMA composites were also prepared at different kneading durations. The results of measurement on processing properties (torque), mechanical properties (tensile properties, notched impact strength) and the study of morphology are commented in this article as a function of composition and technological conditions of composites preparation.
