ABSTRACT:
A poly(.alpha.-aminoacetamide) ("poly(AAMID)" for brevity) main chain having terminal polysubstituted piperidinyl chain ends are novel compounds which have highly desirable UV-light stabilizing (UV-S) activity coupled with unexpectedly good thermal stability. These compounds, referred to as "piperidinyl-chain ended poly(AAMID)s", are oligomers which contain from 2 to about 18 AAMID repeating units, for use in polymer recipes to formulate a stabilized polymeric composition comprising a UV-light-degradable organic polymer containing an effective amount of the poly(AAMID) sufficient to stabilize the polymer. A poly(AAMID) is especially effective in a polyolefin in which there is from about 0.1 percent by weight (% by wt), to about 5% by wt of the oligomer, and is also effective in a wide variety of pastel colored and/or transparent commercially significant polymers.
