Investigations of the influence of compatibilizer and filler type on the properties of chosen polymer blends

The properties of the polymer blends depend significantly on the type of the components and also on the mixing method including the order of the components adding. That kind of influence manifests especially in the change of the mechanical, thermal and processing properties. The basis condition for reaching the homogeneity, specific structure and the properties of a polymer material is its mutual miscibility of the polymers. Additional agents that make mixing easier are usually applied; they have reactive effect which results in a chemical modification of output polymer along with the change in its chemical structure and the structure of macrochains. In order to achieve this, the polyvinylpyrrolidone (PVP) with low molecular mass (12 ± 2 k) has been used. PVP is characterized by high ability to create complexes which is the reason that it has been applied for the medicine as an agent with high sorption ability and in the textile industry for stabilizing of colouring agents. Polybond 3150-thermoplastic maleic anhydride has also been used as a compatibilizer used as a chemical agent coupling the modification of the polypropylene (PP) homopolymer. It is a stabilizer both for the manufacturing processes and the one that improves the resistance to ageing and to high temperature. Within the work some results of chosen properties of PP and polyamide (PA) and PP/PA blends with different percentage composition with the addition of polyvinylpyrrolidone as well as polybond have been presented. The investigations for the influence of the fillers of different types on the properties of prepared blends have also been conducted. As a filler a glass fibre with its symbol E made of the boron-aluminium-silicon E-glass with the alkaline oxides content of less than 1% and titanium white (TiO2) have been used.
