ABSTRACT:
Esters of monoacetals of pentaerythritol. The monoacetals result from the reaction of a 4-hydroxyphenylpropionaldehyde and pentaerythritol, and the further reaction of this monoacetal with either of two particular acid chlorides yields the esters of the invention. These esters are useful, in small proportions, to stabilize polymer compositions, especially olefin polymers.
