| Description
| - Thermal properties of new materials usually determine their applicability to special purpose. In order to follow the influence of the composition on the thermal decomposition pattern of segmented polycarbonate-polyurethanes (PC-PUs), a series of unfilled and filled elastomers based on different polycarbonate diols and their mixtures, hexamethylene diisocyanate and 1,4-butane diol as chain extender were synthesized. Hard segment (HS) content in final materials was in the range from 8 to 35 wt.%. Nanocomposites were obtained by dispersion of organically modified bentonite additive (1 wt.%). Thermogravimetric analysis coupled with differential scanning calorimetry (TG–DSC) was used to study the influence of macrodiol chain constitution, HS content and bentonite addition on the decomposition of PC-PUs under dynamic temperature conditions. It was found that the highest thermal stability belongs to the elastomers prepared without chain extender. The decomposition temperatures (To) of PC-PUs increase with decreasing HS content. The significant enhancement of thermal stability is achieved in polyurethanes with higher HS content and well dispersed nano-scale layered bentonite particles. The regularity in thermal decomposition pattern and the hard segment content is used to determine the composition of polyurethane materials.
