Abstract
Official abstract text for this publication.
This invention relates to novel electron deficient olefins, such as certain 2-cyanoacrylates and methylidene malonates, prepared using an imine or an iminium salt.
First claim
Opening claim text (preview).
What is claimed is: 1. One or more compounds selected from the group consisting of 2. A composition comprising: (a) or more compounds of claim 1 ; (b) a stabilizer package comprising at least one of a free radical stabilizer and an anionic stabilizer; and (c) optionally, one or more additives selected from the group consisting of cure accelerators, thickeners, thixotropes, tougheners, thermal resistance-conferring agents, and plasticizers. 3. The composition of claim 2 , further comprising a coreactant. 4. The composition of claim 3 , wherein the coreactant is a member selected from the group consisting of epoxides, episulfides, oxetanes, thioxetanes, dioxolanes, dioxanes, isocyanates, maleimides, oxazolines, (meth)acrylates, acrylamides, cyanoacrylates, methylidene malonates, vinyl ethers and combinations thereof. 5. The composition of claim 4 , wherein the cyanoacrylate is within structure IV: wherein in this connection R 1 is selected from C 1-16 alkyl, alkoxyalkyl, cycloalkyl, alkenyl, alkynyl, arylalkyl, aryl, or haloalkyl groups. 6. The composition of claim 4 , wherein the cyanoacrylate is selected from methyl cyanoacrylate, ethyl-2-cyanoacrylate, propyl cyanoacrylates, butyl cyanoacrylates, octyl cyanoacrylates, allyl cyanoacrylate, β-methoxyethyl cyanoacrylate and combinations thereof.
