Development of Biocidal Compositions on the Basis of PVC Stabilized With Epoxy-Containing Compounds

The glycidyl ethers of phenyl(benzyl)cyclopropyl carbinol have been synthesized and the compositions on the basis of PVC with use of them as biocidal stabilizers have been developed. The influence of the synthesized epoxy compounds on the critical dissolution temperature of emulsion PVC in the binary mixture consisting of dioctylphthalate (DOPh) and epoxy compounds has been studied and an extreme dependence of the critical dissolution temperature on the quantity of the introduced complex stabilizers has been revealed. Some physical-mechanical properties of the films made from compositions have been determined and it has been established that the used binary mixtures may be of interest as plasticizing and stabilizing systems for PVC. It has been revealed that the joint use of the synthesized epoxy compounds and the complex stabilizer (Ca and Zn stearates) in PVC leads to a synergetic effect – the compositions exhibit fungus resistance. It is assumed that the biostability of the made polymer compositions is directly connected with their composition and is appeared as a result of the simultaneous interaction of all components of the composition.
