Abstract
A polymerizable monomer adhesive composition includes a 1,1-disubstituted ethylene monomer and at least one slip additive, where the slip additive causes a polymer film formed from the monomer to have a lower coefficient of friction than in an absence of the slip additive. The slip additive can be selected from, inter alia, fluorinated monomers or polymers, fluorinated additives, siloxane-containing monomers or polymers, siloxane-containing additives, fluorinated siloxanes, and long chain fatty acid esters. The slip additive can also form a second phase in a resultant polymer film, where the second phase is soluble in the monomer but is insoluble or substantially insoluble in the polymer.
