Abstract
Nonylphenyl neopentylene phosphite, or stated in terms of systematic nomenclature 5,5-dimethyl-2-nonylphenoxy-1,3,2-dioxaphosphorinane, compositions effective to stabilize cellulose ester resins against the degradative effects of heat and processing are disclosed. In accordance with the present invention, preferred stabilizing compositions for cellulose ester resins include nonylphenyl neopentylene phosphite in combination with epoxidized linseed oil. These stabilizing compositions demonstrate their stabilizing effectiveness by maintaining the melt viscosity of the polymer during hot working and minimizing discoloration of the polymer when heated.
