Claims
- 1. Composition comprising (A) an aldehyde or imine of the formula
- R.sub.3 Q.sub.n
- wherein n is 1-4; R.sub.3 is an organic radical having a valence of 1-4; Q is of the formula ##STR14## wherein A is O or NR.sub.4 ; R.sub.1, R.sub.2, and R.sub.4 are independently selected from C.sub.1-6 alkyl or aryl radicals or mixtures thereof; and (B) a transition metal ion selected from the group consisting of Co.sup.++, Cu.sup.++, and Mn.sup.++, wherein said composition has the characteristics of an oxygen scavenger in the polymerization of one or more vinyl unsaturated monomers, oligomers and/or polymers in the presence of oxygen.
- 2. Composition comprising (A) an aldehyde and (B) a transition metal ion selected from the group consisting of Co.sup.++, Cu.sup.++ and Mn.sup.++, wherein (1) said composition has the characteristics of an oxygen scavenger in the polymerization of one or more vinyl unsaturated monomers, oligomers and/or polymers in the presence of oxygen and (2) said aldehyde is selected from the group consisting of ##STR15## wherein R.sub.1 and R.sub.2 are selected from methyl, ethyl, butyl, and mixtures thereof, and m is 4 or 7; ##STR16## wherein R.sub.9 is methyl, ethyl, or butyl; ##STR17## wherein R is methyl, a 1/1 mixture of ethyl and butyl, or a 0.82/0.09/0.09 mixture of methyl, ethyl, and butyl; ##STR18## wherein R is methyl or ethyl; ##STR19##
- 3. Oxygen scavenging composition comprising a mixture of aldehydes which are the reaction product of (a) ethylene urea, (b) formaldehyde, (c) isobutyraldehyde, and (d) 2-ethylhexanal in a molar ratio of (a):(b) of 1:2 and of (a) to the sum of (c) and (d) of 1:2.
