Abstract

Along with the use of plasticizers in the development of polymeric materials with specific properties, special substances such as fungicides are also used because of the negative impact on the polyvinyl chloride materials of microorganisms.

In the present work, the possibility of practical application of butylbutoxyethyl phthalate (BBOEP) and dibutoxyethyl adipate (DBOEA) as plasticizers, and 4-amino-1,4,5,6-tetrahydro-1,2,4-triazinone-5 as a fungicide, in PVC films. The first additive was obtained by the esterification of phthalic anhydride (adipic acid) with hydroxyethyllylated butanol. The second additive was obtained on a base of ethyl monochloroacetate.

According to the conducted experiments, it was it was found that when exposed to mold fungi, some physic-mechanical characteristics of plastic compounds deteriorate.

During the study of the resistance to fungi of plastic compounds, it was found that compositions made on the basis of PVC with BBOEP have got high funginertness, while compositions prepared with using of DBOEA turned out to be unstable against to microorganisms. For the prevention infection by the fungus of the obtained plastic compounds based on adipic acid, a proposed fungicide was used. Primary studies have shown that DBOEA with the addition of the fungicide for resistance to fungi is not inferior to BBOEF.
