Polymer composites are the materials that can be successfully used in the places where high mechanical strength and chemical resistance as well as low absorbability are required. These unique features of polymer composites are obtained mainly due to a suitably selected binder, i.e. a synthetic resin. At the same time, this component accounts for the high production costs of these materials. Partial substitution of the resin with glycolisates obtained using poly(ethylene terephthalate) waste (PET), helps reduce the price of polymeric mortars, while maintaining favourable physicomechanical properties. This modification method also has a beneficial effect on the environment, as it allows the utilisation of a very common waste, which is difficult to dispose of. The article concerns three types of resin mortars, i.e. epoxy, polyester and polyester with the addition of colloidal silica, modified with PET glycolisate. On the basis of the obtained data set and database knowledge mining techniques, such as discriminant analysis and decision trees, it was shown to what extent the type of resin and the presence of an added modifier differentiate the mortar properties. The results obtained with both methods were compared. It was confirmed that these techniques are effective both in the classification and prediction of the type (selection) of mortar in the process of designing new composites.

W referacie przedstawiono możliwości wykorzystania Metody Analizy Skupień do określania i prognozowania cech technicznych zapraw polimerowych. Komputerową analizę numeryczną wykonano dla zapraw polimerowych o określonych właściwościach, poddając analizie wybrane cechy i porównując uzyskane wyniki z wartościami rzeczywistymi. Sposób i metodyka prowadzonej analizy może być zastosowana do podobych bądań, w szerszym zakresie.

The paper describes possibilities of the utilization of the Method of Cluster Analysis to qualifying and predicting of technical properties of polymer mortars. The computer numeric analysis was made for polymer mortars with known properties. The analysis was made for some properties and results were set against with real values. The method and methodology of analysis can be used to similar research, in the wider range.
