AB  - Thermal degradation properties of 5-(4-substitutedphenylazo)-3-amido-6-hydroxy-4-methy1-2-pyridones and 5-(4-substitutedphenylazo)-3-cyano-6-hydroxy-4-methy1-2-pyridones dyes, differing in electron withdrawing and electron donating substitttents in para-position of diazo components were examined. The structure of the synthesized compourtds has been confirmed by H-1 NMR,C-13 NMR, FITR, UV-Vis and XRD analysis techniques. The results obtained with thermogravimetric analysis (TGA) - derivative thermogravimetry (DTG) and differential thermal analysis (DTA) were combined with GC-mass spectral fragmentation to obtain thermal decomposition mechanism. Non-isothermal kinetics were monitored by application of TGA-DTG-DTA. For Kinetic behavior of the investigated dyes during their degradation in an inert atmosphere, Kissinger, Ozawa, Flynn-Wall-Ozawa (FWO) and Kissinger-Alcahira-Sunose (KAS) isoconversional (model-free) methods were applied. It was found that different thermal stabilities of investigated dyes are the consequence of their different chemical structures, including diverse substituents.

AB  - We report on the possibility to build hierarchically organized three-dimensional (3D) titania spherical particles having high surface-to-volume-ratio, by aerosol processing of nanotubular building blocks. Morphology and crystal structure of titania based spherical assemblies, obtained in the temperature range from 150 to 650 degrees C, were characterized by means of scanning and transmission electron microscopy, x-ray powder diffraction and Raman spectroscopy. Initial shape of 1D building units, nanotubes, was well preserved in the spherical assemblies processed at 150 and 450 degrees C. Processing at 650 degrees C resulted in a collapse of the nanotubular building blocks and formation of the assemblies of irregularly shaped TiO2 nanoparticles. Structural analysis revealed several phase transitions in titania spherical assemblies in course with the temperature increase indicating possibility of in-situ phase composition adjustment during aerosol processing.

AB  - The aim of this study was to investigate the influence of different components of interpenetrating polymer networks (IPNs) on their behavior in dual curing automotive applications. Dual curing is one of possible ways to obtain fast curing, scratch resistant coatings for use in OEM and car refinish applications. Dual curing systems, upon hardening, represent interpenetrating networks (IPNs) [1]. IPN's were obtained using novel acrylate-terminated hyperbranched polyester with high functionality and compared to classical 2-pack polyurethane clear coat. In our previous manuscript [1] we investigated the influence of the acrylated hyperbranched polyester (HBP(A)) content in dual curing systems. In this article we studied the influence of the reactive diluent on dual curing compositions. To this end, we have chosen IPN with 50/50 weigth ratio of polyurethane (PU) and polyacrylic (PA) component. In order to determine more clearly the role of the HBP(A) in one IPN HBP(A) was changed with hexane diol diacrylate (HDDA), keeping the same ratio with EHA. The IPNs were characterized by dynamic-mechanical analysis (DMA), differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). The mechanical properties of the IPNs were also investigated. The IPN with HDDA as reactive diluent, had the best performance. IPN with H BP(A) had the highest glass transition temperature Tg and the highest crosslink density, but it did not have the highest hardness.

AB  - The aim of this study was to investigate the possibility of using acrylated hyperbranched polyesters (HBP) as UV curable component in dual curing automotive applications. Dual curing is one of possible ways to obtain fast curing, scratch resistant coatings for use in OEM and car refinish applications. Dual curing systems, upon hardening, can give interpenetrating networks (IPNs). All the IPNs were obtained by UV-thermal dual cure process and they consisted of an UV curable acrylic component and a classic 2-pack urethane component. The acrylic component was acrylated hyperbranched polyester (HBP(A)) and 2-ethyl hexyl acrylate (EHA). The classic 2-pack urethane component consisted of a hydroxyl functional acrylate copolymer (HA) and Desniodur (R)) N3390. The weight ratio of HBP(A) and EHA in the IPNs was varied from 100/0 to 25/75, while the urethane component remained the same in all the IPN samples. The IPNs were characterized by dynamic-mechanical analysis (DMA), differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). The mechanical properties of the IPNs were also investigated. A single glass transition temperature, T-g, indicated that a homogeneous material with no separation domain was obtained. DMA showed that with increasing HBP(A) in the IPNs, the crosslink density increased, while the flexibility decreased. The data obtained by DMA and DSC showed a decrease of the T-g values with increasing amount of HBP(A). There were slight differences in the thermal stability of the IPNs.
