  • Free radical polymerizable compositions including para-halogenated aniline derivatives
    Patent number: 5932638
    Abstract: The present invention provides adhesive compositions which include free radical polymerizable compounds and a redox catalyst system to accelerate polymerization thereof. The redox catalyst includes an aniline derivative substituted in the para position by halogen as an accelerator. The use of para-halogenated aniline derivatives as an accelerator in the cure of free radical polymerizable compounds results in good bond strength and greatly improved surface cure of the adhesive composition.
