COMPOSICION DE POLIMERO,ESTABLE CON RESPECTO A LA DECOLORACION TERMICA Y METODO PARA ESTABILIZARLA

摘要

A polymer composition containing a high proportionate amount of olefinic nitrile is stabilized against thermal discoloration by inclusion therein from about 0.05 to 2 parts by weight per hundred parts of resin of an organotin maleate compound selected from the group consisting of the hydrocarbon tin maleates and the hydrocarbon tin-bis-maleate half esters.
