On the basis of models developed and experimental studies, the impact of a compression garment on average and local changes in unit pressure was analysed. The study was based on the analysis of the results of 3D scans of selected parts of female and male bodies. It was found out that surface pressure exerted by the compression garment leads to some changes in the geometry of body circumferences and in their lengths and, consequently, to a change in the average pressure value, as well as local changes along the circumference. The main purpose of this work was to estimate the size of these changes in the example of selected parts of female and male bodies.

The synthesis of polymer brushes containing poly (methyl methacrylate) (PMMA) chains grafted from hydroxyapatite (HAP) particles was disscussed. Surface of commercially available hydroxyapatite was first modified with atom transfer radical polymerization (ATRP) initiator and hydrophobized with isobutyric acid, and then surface-initiated ATRP was conducted. Properties of obtained hybrids were studied by dynamic light scattering (DLS) and gel permeation chromatography (GPC). Polymers with various molecular weight up toMn=96,100 g/mol were obtained with good control;Mw/Mn<1.2. Copolymer brushes of poly (methyl methacrylate-stat-benzophenone methacrylate) (P(MMA-stat-BPMA) were also synthesized and cross-linking ability of such materials under UV radiation was confirmed.
