Compositions of Arylalicyclic Copolyimide with Alkylated Monthmorillonite

The results of studies on the preparation and study of the properties of composite materials based on compositions of arylalicyclic copolyimide and alkylated montmorillonite (AMM) modified with polyethylene glycol to increase the affinity of a natural mineral to polymer matrix are presented in the work. It was found that an increase in the compatibility of composition’s components is due to the addition to copolyimide solution of previously prepared mixture of alkylated montmorillonite in 5 % and 2 % polyethylene glycol solution in methylpyrrolidone.

LIGHT AND SPACE COMPOSITION OF LE CORBUSIER'S SACRED BUILDINGS

The article discusses the ways, methods and means used by architect Le Corbusier to organize the light environment in his sacred buildings: the chapel of Notre Dame du Haut in Roncham; the church of the Dominican monastery complex Notre Dame de la Tourette; the Catholic church of Saint-Pierre-de-Firmin. The churches were built in France in the 50s and 70s of the last century, with the exception of the church in Firmin, which was completed in 2006.

THE STUDY OF PROPERTIES OF SODA PRODUCTION WASTES AS ANTI-ICING REAGENTS

The article considers the possibility of reducing the man-made load on surface and ground waters in Lysychansk-Severodonetsk industrial agglomeration caused by numerous sludge collectors and tailings storage facilities of various industries formed many decades ago. The paper provides information on the location and technical condition of the sludge collectors of the liquidated "LYSSODA" manufacture (Luhansk oblast), the amount of waste currently stored in them as well as the impact of these wastes on the quality of groundwater in the area where the sludge collectors are located.

PORTALS IN DECORATION OF BUILDINGS OF THE ASSEMBLY OF THE ASSUMPTION OF THE VIRGIN IN LVIV

In artistic and stylistic terms, the architecture of Lviv's sacred buildings during the 16th-18th centuries was marked by a variety of appearances. The builders paid great attention to the plastic expressiveness of the building. The facades of sacred buildings were richly decorated, had a clear system of horizontal divisions of cornices and belts, carved in stone with ornamental carvings window frames, and portals of entrances.

IMAGE AND FONT COMPOSITION IN GRAPHIC IDENTIFICATION OF PACKAGING

The article highlights the topical problems of searching for new methods of using font and image elements in project design methodology of compositional integrity of graphic identification development for packaging of consumer goods.

Research purpose of the article is to outline and investigate the methods of reflecting identification of packaging with the help of author's unique image and font composition.

HISTORICAL AND ARCHITECTURAL DEVELOPMENT OF THE EXALTATION OF THE HOLY CROSS MONASTERY IN MANYAVA (GREAT MANYAVSKY HERMITAGE) XVII-XX CENTURIES

The article traces the history of the origin of the Manyavsky Hermitage and reveals the stages of development of the monastery from the beginning of its foundation and formation, prosperity to the decline, destruction and revival in our time. In the course of the research, the architectural-spatial and planning structure of the monastery ensemble of the Exaltation of the Holy Cross in Manyava were analyzed.

Study of the influence of the addition of an exothermic mixture and the ratio of the components of the exothermic mixture on the melting indices at FCAW

An important issue in the processes of strengthening and restoration of surfaces exposed to abrasive, abrasive-corrosive and hydroabrasive wear, using the process of self-protective flux-cored arc welding (FCAW), is to increase the productivity of hardfacing and the quality of the hardfacing metal. The literature review showed that one of the ways to increase the productivity of hardfacing and improve the quality of the hardfaced metal is to add an exothermic mixture to the core filler of flux-cored wire electrode.

INFLUENCE OF MODIFIED EPOXY RESIN ON PHYSICAL AND MECHANICAL PROPERTIES OF EPOXY COMPOSITE

The main physical-mechanical and thermophysical characteristics of composite materials based on epoxy resin ED-20 and peroxide resin ED-20P (modified with tert-butyl hydroperoxide ED-20 of a molecular weight 480) in the ratio of 30 mass parts of ED-20P to 70 mass parts of ED-20 and unsaturated oligoester TGM-3 were researched. Butyl methacrylate was used as the active diluent of epoxy-oligoester mixtures. The polyethylene polyamine was used as hardener in a steochemical ratio. For the comparison we studied compositions which did not contain ED-20P resin.

Theory and practice of obtaining composite materials based on polymer blends

The regularities of the thermodynamic compatibility of various industrially produced polyolefins and heterochain polymers and the possibility of obtaining composite materials based on their mixtures with significantly increased performance properties based on existing production facilities and process equipment have been identified.

Structuring of epoxy-oligoester compositions in the presence of peroxidated epoxy resin.

In order to improve the properties of epoxy resins they are modified by the various compounds, in particular oligoesters. Compositions based on ED-20 epoxy resin and unsaturated oligoesters are structured in the presence of polyethylene polyamine (PEPA). The oligoester acts as a plasticizer that is not chemically bounded to the molecules of spatially crosslinked structure. It leads to the deterioration of their physical, mechanical and chemical properties during the working process of film based on epoxy-oligoester compositions.
