The thermo- and light-stabilizing activity of glycidyloxycarbonyl- and glycidyloxymethylsubstituted derivatives of the sulphur-containing rosin in the compositions on the basis of plasticized polyvinyl chloride were studied. It found that the proposed epoxy-derivative adducts of rosin possess thermal stability allowing them to withstand the processing temperature of polyvinyl chloride compositions. The developments showed that the proposed stabilizers can protect the polymer matrix against light radiation. It revealed that the film samples prepared with the help of the proposed stabilizers showed the high thermal stability, impact resistance, good frost resistance and mechanical strength.
