“…As softener used industrial dioctylphthalate (DOF) and 1,5-dioctoxyethyl phthalate (DOOEF) developed by us earlier. Replacement of DOF by DOOEF was made taking into account the factor of replacement defined earlier [20][21][22][23][24][25][26]. As the stabilizer used barium-calcium stearates, as an excipient -a chalk.…”

In work influence of the main additives (a heat stabiliser, softener, an excipient) on physicomechanical properties of compositions on the basis of polyvinylchloride (PVC) is studied. It is noted that increase in content of additives in a system in the stated quantities leads to change of Shore hardness of A. and melt flow rate. The functional interrelation between the applied additives and properties of plastic compounds is established. The reliability of the received mathematical model and its applicability for prediction of properties of PVC compositions depending on structure of a compounding is proved.

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.

The production of polyvinyl chloride (PVC) requires implication of a large number of plasticizers. Ester compounds are the most suitable for plasticization. Currently the existing range of industrial plasticizers does not satisfy a need of the polymer industry and it is of great importance to develop new plasticizers that meet modern requirements. Therefore, the elaboration of new ester compounds with effective plasticizing properties, is relevant and has not only scientific value, but also practical one. One of the basic requirements for ester plasticizers is their resistance to thermal oxidation. Accordingly, we considered the effect of oxygen at 150 о C (the temperature of conversion of PVC-plastic compounds) on a wide range of oxy-alated alcohol phthalates developed earlier. The first group consisted of aromatic alcohols, the second group-phthalates of oxyalkylated aliphatic alcohols. The first group showed high thermal stability, the latter should be stabilized by the addition of antioxidants. It is known that aromatic hydrocarbon derivatives are widely used as stabilizers of thermooxidative disrupture. The main function of the mentioned compounds is to suppress the catalytic action of air oxygen in energy impacts on polymers and plasticizers. Consequently, we investigated the effect of Agidol-1 on increasing the stability of phthalate plasticizers to thermal-oxidative degradation.
