ABSTRACT:
An organic peroxide stabilizing composition comprises an organic peroxide and an organic peroxide stabilizing compound selected from one of the following general formulas (I) or (II):in-line-formulae description="In-line Formulae" end="lead"?R1CH═CH(CH2)m(CH═CH)n(CH2)oR2 (I)in-line-formulae description="In-line Formulae" end="tail"?in-line-formulae description="In-line Formulae" end="lead"?R4C≡C—C(O)OR5 (II)in-line-formulae description="In-line Formulae" end="tail"?or mixture thereof wherein R1is hydrogen, alkyl of from 1 to about 10 carbon atoms, or aryl of from 6 to about 12 carbon atoms, optionally substituted with at least one halogen, lower alkyl, or hydroxy group; R2is hydrogen, —OH, —C(O)R3or —C(O)OR3in which R3is hydrogen or lower alkyl; R4and R5each independently has one of the meanings of R1and, additionally, R4can be —C(O)OR3; wherein R3has one of the same meanings as above and m is 0 or an integer of from 1 to about 20, n is 0 or 1 and o is 0 or an integer of from 1 to about 20 in an amount sufficient to retard the rate of decomposition of the organic peroxide.
