Abstract:Z modifikacijo pogosto izboljšamo obstoječe lastnosti polimernega materiala, lahko pa dosežemo tudi takšne, ki jih polimerna matrica nima. Uspešnost polimernih modifikatorjev je predvsem odvisna od jakosti interakcij na fazni meji polimer/modifikator. Preučevali smo vpliv polimernih modifikatorjev na polipropilensko matrico. Uporabili smo več vrst in tipov stirenskih blokkopolimerov v koncetracijah do 20 vol.%. Vzorce smo pripravili iz taline v Brabenderjevem gnetilniku in s stiskanjem v plošče na laboratorijski stiskalnici. 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 mešanic polimerov.

Title:Modification of isotactic polypropylene with styrene block-copolymers
Abstract:With a modification the current properties of polymeric material can be improved, and even some new properties can be obtained. The success of polymeric modifiers mostly depend on the interaction intensity at the phase boundary of the polymer/modifier. The influence of polymeric modifiers on polypropylene matrices were investigated. Different sorts and types of styrene block-copolymers were used in a concentration range up to 20 vol.%. Samples were prepared by melt-mixing in a Brabender kneading chamber and were compression molded into plates on a laboratory press. In this article the results of processing properties (torque), mechanical properties (tensile properties, notched impact strenght) are discussed and the morphology in relation to the composition of the polymer blends is defined.
Keywords:polypropylene, polymer modifier, styrene block-copolymers, polymer blends, mechanical properties, morphology
