At anisothermic thermograms registered when curing the urea/formaldehyde (UF) resins in high pressure DSC cell the endothermic effects, such as evaporation of water and elimination of formaldehyde shift to temperatures higher by about 40°C in compar

The conditions of the preparation of formaldehyde/urea (F/U) resins have been supervised with the aim to reduce formaldehyde emission by influencing the ratio of methylene/dimethylene-ether-bridge linkages in the product. The most crucial point of th

A study has been made of the oxidation of APP and IPP in the condensed phase and in 1,2,4-trichlorobenzene solution. The differences in the oxidation rates and hydroperoxide concentrations between the amorphous APP melt and the semi-crystalline IPP w

Condensation process of pentaerythritol / phtalic-anhydride/ benzoic acid/synthetic fatty acid mixture was carried out according to two different schedules; the first was carried out in one step (I) at 210 °C, the other in two steps (II) feeding pen

The initial stage of the phosphoric acid-catalyzed polycondensation reaction of furfuryl alcohol and formaldehyde was studied. The overall kinetics of monomer-consuming reactions were investigated in dependence of the initial monomer ratio and the te

We studied the effect of an inert solvent (benzene) on the overall rate of copolymerization in the system styrene/diethylmaleate (ST/DEM), initiated with azo-bis-iso-butyro-nitrile (AIBN) at 50°C. The experimental results can be interpreted on the h
