Abstract
Our study of influence of pigments on thermal degradation of polyacetal resin showed that most of all pigments have tendencies to accelerate the degradation.
This effect of acceleration was proved to be caused by both factors, the metallic components in pigments and the pH value of pigments, which was expected to have influence upon the hydrolysis at ether bond. Therefore the pigments containing copper, lead and zink etc, or the pigments having the strong acidity have remarkable influences for acceleration of thermal degradation upon polyacetal resin.
