Volatility in agricultural production caused by the reliance on natural factors, and water is one of the basic, which provides greater production. The authors in their professional praxis have seen that the presence and absence of vadose zone in the upper part of aquifer, with inter-granulary porosity type, is a prerequisite for enhanced concentrations of iron and manganese in groundwater.

AB  - Two kinds of aqueous acrylic polyols (single step and multi step synthesis type) have been investigated for their performance in the two-component aqueous polyurethane application, by using more selective catalysts. The aliphatic polyfunctional isocyanates based on hexamethylen diisocyanates have been employed as suitable hardeners. The complex of zirconium, commercially known as K-KAT(R)XC-6212, and manganese (III) complexes with mixed ligands based on the derivative of maleic acid have been used as catalysts in this study. Both of the aqueous polyols give good results, in terms of application and hardness, when elevated temperatures and more selective catalysts are applied. A more selective catalyst promotes the reaction between the isocyanate and polyol component. This increases the percentage of urethane bonds and the degree of hardness in the films formed from the two components of aqueous polyurethane lacquers. The polyol based on the single step synthesis route is favourable concerning potlife and hardness. The obtained results show that the performance of the two-component aqueous polyurethane coatings depends on the polymer structure of the polyols as well as on the selectivity of the employed catalyst.

AB  - The thermal stability of aqueous polyurethanes has been measured applying the thermogravimetric analysis. The aqueous polyurethanes (aqPUR) with catalysts of different selectivity have been studied by use of the dynamic method. To obtain degradations of 0.025, 0.05, and 0.10, employing the dynamic method, the heating rates of 0.5, 1, 2, 5, and 10 degrees C min(-1) have been used in the range of 30-500 degrees C. Using the more selective catalysts in the aqueous polyurethanes, the total resulting time of the decompositon has been on the increase at all degrees of the degradation and at the particular starting temperature. This paper shows that the dynamic method based on the thermogravimetric analysis can be used to assess the thermal stability of the aqueous polyurethanes using the catalysts of different selectivity.

AB  - The latest investigations on producing more efficient catalytic aqueous polyurethane systems are in the domain of metal complexes with mixed ligands. In our previous research works, the high selectivity for the isocyanate-hydroxyl reaction in aqueous polyurethane systems has been shown by the manganese(III) mixed-ligand complexes. The two new complexes have been prepared with two acetylacetonate (acac) ligands and one maleate ligand and its hydroxylamine derivative of the general formula [Mn(C5H7O2)(2)L]. Their structures have been established by using the fundamental analyses, the FTIR and UV/VIS spectroscopic methods, as well as the magnetic measurements. In order to explain the different selectivity of the manganese(III) mixed-ligand complexes, the UV and ESR spectroscopy have been employed to determine the kinetics of the complexes' decomposition. The thermal stability of the complexes has been determined by way of the dynamic TG method at the heating rate of 5 degrees C.min(-1) and at the temperature ranged 20-550 degrees C. It suggests the decomposition of the complexes by loss of acid ligand. The main factor in the selective catalysis control in the aqueous polyurethane systems is the nature of the acid ligands and their impact on the manganese(II)/manganese(III) equilibrium.

AB  - The FTIR spectroscopy has been employed in this research work to monitor the process of nitrodope photodegradation, by measuring surfaces of bands typical of a nitro group. Nitric esters are subject to degradation, which is reflected on a quantitative ratio of the surfaces of the IR bands that originate from the nitric ester. The obtained results show that the length of the UV rays activity on the samples over time intervals of 240, 480 and 960 min. directly affects the spectrum appearance of the same sample before and after the radiation. The longer the UV rays activity time and the larger a mass proportion of nitrocellulose in the nitrodope is, the smaller the bands surface becomes i.e. the degree of degradation is higher. To confirm the degradation of nitrodope the degree of reticulation has also been examined by determining the König hardness.
AB  - U radu je korišćena FTIR spektroskopija za praćenje procesa fotodegradacije nitrolakova, merenjem površina traka koje su karakteristične za nitro grupu. Nitratni estri podležu degradaciji što se odražava na kvantitativni odnos površina IR traka koje potiču od nitratnog estra.

abstract = "The FTIR spectroscopy has been employed in this research work to monitor the process of nitrodope photodegradation, by measuring surfaces of bands typical of a nitro group. Nitric esters are subject to degradation, which is reflected on a quantitative ratio of the surfaces of the IR bands that originate from the nitric ester. The obtained results show that the length of the UV rays activity on the samples over time intervals of 240, 480 and 960 min. directly affects the spectrum appearance of the same sample before and after the radiation. The longer the UV rays activity time and the larger a mass proportion of nitrocellulose in the nitrodope is, the smaller the bands surface becomes i.e. the degree of degradation is higher. To confirm the degradation of nitrodope the degree of reticulation has also been examined by determining the König hardness., U radu je korišćena FTIR spektroskopija za praćenje procesa fotodegradacije nitrolakova, merenjem površina traka koje su karakteristične za nitro grupu.
