| Popis: | The possibilities of improving the properties of binding materials based on polyvinyl acetate and its derivatives are considered. It is shown that an enhancement of the quality of polyvinyl acetate glues for tobacco industry can be achieved through changes within certain limits of formulation and technological parameters of the vinyl acetate polymerization process. It is found that using modified polyvinyl alcohol as a polymer additive for grouting mortars favors the improvement of their quality. In the oil industry, this additive enhances the adhesion of grouting mortar with a contact surface of a well-producing zone and reduces water trapping. An investigation was conducted of the production process of polyvinyl butyral, which carries different amounts of acetate groups; as a result, the conditions of synthesis for achieving the optimal content of these groups are defined. It is shown that a high content of acetate groups gives one the ability to significantly improve the physicomechanical characteristics of the films based on polyvinyl butyral. |
