CYANOACRYLATE ADHESIVES WITH IMPROVED THERMAL PROPERTIES IN HARDENED CONDITION CONTAINING A SUBSTITUTED AROMATIC COMPOUND

摘要

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 mono, poly or hetero aromatic compound characterized by at least three substitutions on an aromatic ring thereof, two or more of said substitutions being electron withdrawing groups selected from the group consisting of NO2, CN, CF3, NR13+, SR12+, C(=O)R1, C(=O)OR1, NO, CCl3, SO2, S(=O), SO3, SO2R1, SO2OR1 and F, one or more of said substitutions being leaving groups selected from the group consisting of F, Br, Cl, I, NO2, CN, SOR1, SO2R1 and SO2OR1, and R1 is an optionally substituted hydrocarbon group. Example such compounds have the formula: CHEM where L is the leaving group and the W groups are the electron withdrawing groups.
