The diploma thesis is focused on the comparison of the influence two-component and one-component waterborne base coatings on the quality of pigmented finished surface in high gloss. There are analyzed requirements for the mentioned surface treatment and applied coatings in the thesis. Samples preparation, depending on base coating and base material used and determination of the physical-mechanical, chemical and optical properties are indispensable part of the diploma thesis. The selected base coatings are compared with each other and with commonly used polyester and polyurethane coatings.

The diploma thesis deals with a detailed study of he esterification reaction between PVAl and acrylic and methacrylic acids. Tha goal is to prepared PVAl-based macromers bearing (meth)acrylic moieties bound to PVAl macromolecular backbone. Attention will be paid especially to equlibrium establishing times and to the influence of reaction mixture composition on the properties of resulting products.

This diploma is devided into two major parts. Theoretical and practical. In the theoretical part I consider the meaning of touch which is ambiguouse. Fist of all it should express, by the form of art, our desire and necessity to establish into relationship with another human-being, get in touch and get to know each other. By the time of working at this cycle my form is beginning to change. Touch doesn´t only express relationship but they´re also recording my touching, getting to know myself. The practical part of my thesis focus on production figures. It consists of a cycle of paintings, fiberboard of various sizes made by acrylic technique. These paintings capture directly human bodies in positions of touching, proximity, delay. They capture the joy in positions of direct touch againts deprivation when a person is deprived of contact with another person. The starting point of this thesis is personality and emocionality.

Diploma thesis is focused on modification and characterization of polypropylene (PP) products surfaces by the chemical way. In theoretical part of thesis are summarized the current knowledge of this topic including characterization methods. Polypropylene surfaces were modified by acrylic monomers (acrylic acid, acrylic acid with 20 mol% content of sodium acrylate and acryl amide). Modified surfaces were characterized by infrared spectroscopy with ATR technique. The comparative parameter was carbonyl index determined from absorption peaks of functional methyl groups (2950 cm-1 ) and functional carbonyl groups (1700-1750 cm-1) of FTIR-ATR spectra. Determination of effect of initiator concentration on the modification process was done for acetophenone and benzophenone. There were determined the time dependence of carbonyl index for time from 0 to 600 s of mentioned monomers. In the same condition were modified test specimens designed for preparation of adhesive joints. Joints were bonded by cyanoacrylate adhesive that provide reaction with surface of polyacrylic acid. There were founded conditions of modification that provided strength of adhesive joints higher than strength of original PP. There were identified changes of surface roughness by using of confocal microscopy.

The goal of this master's thesis was to develop a method for gas chromatography using the Controlled Evaporation Mixer (CEM) for gas mixture sampling. Gas mixture contained chemical substances formed during manufacturing of acrylic acid by two-step oxidation of propylene. The analyzed mixture composed of permanent gases, light hydrocarbons and compounds containing oxygen. During the method development several capillary columns with polar and nonpolar stationary phase were used. After selection of the most suitable column (SPB-1 Sulfur, Supelco, USA) the method was further optimized for the maximal possible separation efficiency. However, it was impossible to separate propane and propene on SPB-1 Sulfur column. These gases were possible to determine on TCD detector and separate on respective columns prior to the detector. For that purpose, the optimization of multiple-port valves switching inside the gas chromatograph was performed. The next step was calibration of gas chromatograph for a purpose of quantitative analysis of selected substances. The calibration solution containing solvent and an analyte was evaporated and diluted with nitrogen by CEM to obtain desired analyte concentration. Formaldehyde and propane had a very low response on detectors, acetaldehyde was undetectable in desired...
