Abstract
Abstract An anaerobic composition on the basis of a polymerizable oligomer of the acrylic series, which comprises a polymerization inhibitor, a polymerization initiator combined with a polymerization accelerator, and a plasticizer, wherein, in accordance with the invention, the polymerizable oligomer of the acrylic series is at least one oligocarbonateacrylate of the general formula CH.sub.2 ═ C(X)COORO[COOR'OCOOR"O].sub.n COOR'OCOOROCOC(X) ═ CH 2 where X is --H, --CH 3 or a halogen; R is a glycol or bisphenol radical; R' is a glycol, bisphenol or polyol radical; R" is an alkyl or aryl radical; n = 0 or ≧ 1; The polymerization inhibitor is bis(5-methyl-3-tert.butyl-2-oxyphenyl)methane; the polymerization initiator is benzoyl peroxide combined with ferrocene as the polymerization accelerator taken in a ratio of from 1:1 to 1:0.005; and the plasticizer is a polymerizable acrylic acid ester of the formula R'" --OOC--C(CH.sub.3)═CH.sub.2 where R'" is alkyl radical C 8 -C 12 .
