    Abstract: This invention relates to novel UV absorbers, their methods of preparation, their use in stabilizing polymers and polymers so stabilized against the degradative effects of UV light. The novel compounds of formula I are oxamides which are substituted on one or both nitrogens with
    a 2-hydroxy-3-(2H-benzotriazol-2-yl)benzyl group. The 2-hydroxy-3-(2H-benzotriazol-2-yl)benzyl groups are efficient UV absorbing groups and the oxamide group contributes additional light stabilizing, heat stabilizing and metal complexing properties to the compounds. The compounds have low-volatility and are especially useful as UV stabilizers for engineering resins processed at high temperatures.

    Abstract: Novel unsaturated peroxide compositions of Structure A,
    are disclosed where the R-Q- grouping contains a polymerizable carbon-carbon double bound, i.e. R is, inter alia, alkyl of 1 to 18 carbons; Q is, inter alia,
    where -(X-Ri) shows the point of attachment of the X-R 1 group and (R)- shows the point of attachment of the R group to the Q diradical and R 2 and R 3 include hydrogen; -X- includes a direct bond and -R 1 is a peroxide-containing radical, e.g.,
    wherein R 6 , R 7 , R 8 and R 9 are, inter alia, alkyl of 1 to 4 carbons and R 10 includes t-alkyl of 4 to 12 carbons. Further, polymeric peroxide compositions derived from them and their uses are disclosed.
