Abstract (English):
Influence of aluminum and magnesium hydroxides on stress-strain, technological properties and on thermal stability of PVC plasticates is probed. Sinergizm dealing of effect, on an index «thermal stability» is revealed, when using a compound of aluminum and magnesium hydroxides in the presence of stearic acid, or calcium stearate. As the effect of inhibition of growth rate of polyolefinic sequences in polymer macrochains, at the expense of substitution of labile atoms of chlorine in the PVC is shown, to being formed in situ by stearate of coordinately unsaturated metal, in this case aluminum.
