| Summary: | The aim of this work is to determine the effect of polyvinylpyrrolidone, polyacrylic acid, acrylic and methacrylic acid compositions on the swelling polymers with PVA, as well as the influence of environment, close to the body (temperature, saline) on swelling as a parameter that determines the subsequent dissolution of the sample in the wound, lasting up to 10 days and it is difficult to control. As a result of experimental studies found that the use of polyacrylic acid and polyvinylpyrrolidone is most preferred to generate multifunctional composite materials based on polyvinyl alcohol. The quantitative values of the reduced components and their influence on the properties of the developed material. Found that swelling occurs in saline at a higher rate and to a greater degree of swelling parameters are found which allow to consider the influence on the behavior of the environment of the body of biodegradable polymer materials. |
