Abstract:

The results of investigations of the influence of nature of the modifikator and his amount are brought for a calcium carbonate, as filler of polypropylene. It has been shown that in a number of the used coupling agents: tetrabutoxytitanium, tetrastearateacyloxytitanium, tris[tri(butoxy)titanoxy]borane and substitution products in the last butoxygroups on the remains of the stearic acid, the higher the physico-mechanical properties of the composite based on polypropylene, namely: tensile strength – up to 82,1 Mpa, impact strength Charpy – up to of 59,0 kJ/m2, achieved by using as the dressing of tris[tri(butoxy)titanoxy]borane. This fact is caused both by slowing down the destructive processes in the matrix of polypropylene, and forming additional grid stronger coordination bonds between the boron atom in the structure of coupling agents and oxygen filler and degradation products of polypropylene matrix.

Keywords: polypropylene, calcium carbonate, modifikator, properties, composite.
