A cyanoacrylate monomer adhesive formulation which has improved thermal properties resulting from the inclusion in the formulation of an effective amount for enhancing the thermal resistance of the cured polymer of a sulfur containingcompound of the formula: R1O-SO2-OR1 (see fig.I) R1O-SO-OR1 (see fig. II) R1-SO-R1 R1-SO-OR1 or (see fig. III) where R1 and R2 are, respectively, monovalent and divalent hydrocarbon groups which may be optionally substituted with halogen, NO2, oxo, CN, alkoxy, hydroxy, acyloxy or SO2.

Divulgation d'une formulation d'adhésif monomère au cyano-acrylate qui affiche des propriétés thermiques améliorées résultant de l'inclusion dans la formulation d'une quantité efficace pour accroître la résistance thermique du polymère durci d'un composé contenant du soufre de la formule : R1O-SO2-OR1 (voir fig. I) R1O-SO-OR1 (voir fig. II) R1-SO-R1 R1-SO-OR1 (voir fig. III), dans laquelle R1 et R2 sont, respectivement, des groupements hydrocarbonés monovalent et divalent, qui peuvent être substitués facultativement par un halogène, NO2, un oxo, CN, un alcoxy, un hydroxy, un acyloxy ou SO2..
