In the work presents to test of the possibility of using halogenated vegetable oil to obtain polymeric materials. The result of the conducted research the development of the methodology of halogenation of sunflower oil presented and confirmed of its structure by the method of IR spectroscopy. The obtained halogenated oil was used to reactions of interact with compounds of different functionality. Synthesized materials was using for obtain polymer composite materials by thermopolymerization with vinyl monomers.
The aim of the work was to investigate for the first time the possibility of modification of disperse mineral fillers (chalk and magnesium hydroxide) deodorizing shoulder straps containing fatty acids obtained by refining sunflower oil for create filled polymer composites. In the study of composites based on PVC found an increase in their tensile strength, strength reaches almost 50 % increases. Accordingly, the relative elongation of these polymer composites increases. Shown to increase toughness with increasing content of modifier, with a greater increase in toughness for chalk than magnesium hydroxide for polyester resin composites. The maximum increase of toughness is more than 50 %. Thermomechanical studies have shown that the heat resistance of composites mainly increases with modified fillers.
Метою роботи є перевірка можливості використання відпрацьованої соняшникової олії для модифікування поверхні крейди та гідроксиду магнію та вивчення впливу таких наповнювачів на фізико-механічні властивості полімерних композиційних матеріалів. За результатами досліджень вперше доведено можливість модифікування дисперсних мінеральних наповнювачів відпрацьованою (пересмаженою) соняшниковою олією, не придатною для харчових цілей. Створено полімерні композити на основі поліетилену низького тиску, пластифікованого ПВХ та епоксидної смоли, наповнені крейдою та гідроксидом магнію, модифікованими відпрацьованою соняшниковою олією. Ключові слова: полімерні композити, крейда, поліетилен, ПВХ, соняшникова олія, епоксидна смола. Chobit M., Vasylyev V. Lviv Polytechnic National University, Department of organic chemistry USAGE OF WASTE VEGETABLE OIL FOR MAKING POLYMER COMPOSITES The purpose of this work is to check the possibility of using sunflower oil for modification of the chalk surface and magnesium hydroxide and to study the effect of such fillers on the physical and mechanical properties of polymer composite materials. According to the research results, for the first time the possibility of modification of the dispersed mineral fillers by the used (redone) sunflower oil unsuitable for food was investigated. Polymer composites based on low-density polyethylene, plasticized PVC and epoxy resin were filled with chalk and magnesium hydroxide with modified sunflower oil.
The paper describes the synthesis and investigation of the properties of acrylamide and acrylic acid hydrogel composites with a crosslinking agent with gelatin, unmodified or modified peroxide oligomer, which can be use to create cosmetic products. The method of synthesis of hydrogel composites described and their physical, chemical, thermomechanical properties and graphic representation of these regularities presented. To do this, a series of samples with different ratios of starting substances synthesized and the dependence of their properties on the structure is established.
The purpose of this work was to increase the compatibility of composite components by modifying the surface of hydroxyapatite particles. Оleic acid and peroxide copolymer VEP-MA were used аs modifiers. It was shown that modified composites have higher impact viscosity and tensile strengths.
