A stabilized composition comprising a compound of the formula: ##STR10## wherein Y is alkyl from 1 to 18 carbon atoms, alkenyl or alkynyl of 2 to 8 carbon atoms, a cycloalkyl of from 5 to 8 carbon atoms, aralkyl, or aryl, and X and X are hydrogen, halogen, or a (C 1 -C 4 )alkyl and an effective amount of an epoxide of the formula: ##STR11## wherein R 1 is hydrogen, alkoxyalkyl, 2,3-epoxy dialkoxyalkyl; R 1 may also be a radical of the formula: ##STR12## wherein Z is straight or branched chain lower alkylene or halo substituted lower alkylene of from 2 to 6 carbon atoms; Q is a (C 1 -C 4 )alkylene or carbonylphenylcarboxy; R 2 is hydrogen or R 1 and R 2 or R 1 and R 3 may be joined together with the carbon atoms to which they are attached to form an alkylene chain of from 3 to 7 carbon atoms, which alkylene chain may be substituted with a lower alkylene to form a bicycloalkane, or substituted with a lower alkenyl radical; R 3 is hydrogen or lower alkyl and R 4 is hydrogen.
Claim 2
Dependent Claim
190 words
A stabilized composition comprising a compound of the formula: ##STR10## wherein Y is alkyl from 1 to 18 carbon atoms, alkenyl or alkynyl of 2 to 8 carbon atoms, a cycloalkyl of from 5 to 8 carbon atoms, aralkyl, or aryl, and X and X are hydrogen, halogen, or a (C 1 -C 4 )alkyl and an effective amount of an epoxide of the formula: ##STR11## wherein R 1 is hydrogen, alkoxyalkyl, 2,3-epoxy dialkoxyalkyl; R 1 may also be a radical of the formula: ##STR12## wherein Z is straight or branched chain lower alkylene or halo substituted lower alkylene of from 2 to 6 carbon atoms; Q is a (C 1 -C 4 )alkylene or carbonylphenylcarboxy; R 2 is hydrogen or R 1 and R 2 or R 1 and R 3 may be joined together with the carbon atoms to which they are attached to form an alkylene chain of from 3 to 7 carbon atoms, which alkylene chain may be substituted with a lower alkylene to form a bicycloalkane, or substituted with a lower alkenyl radical; R 3 is hydrogen or lower alkyl and R 4 is hydrogen.
