Abstract
Long chain N,N-dialkylhydroxylamines represent particularly valuable process stabilizers for polyolefin compositions. The hydroxylamine derived from di(hydrogenated tallow)amine is particularly useful for this purpose. These long chain N,N-dialkylhydroxylamines are very resistant to extraction from polyolefin compositions.
