or t butyl catehol for example the inhibitors are normally used in small amounts of from 0 001 to 1 by weight of the monomer it should be noted that the quantity of inhibitor will influence not only the stability in bulk but also the onset of polymerization of the compounds of the present invention and could be used as a means to control the set time the methacrylated or acrylated cyanoacetates of the present invention may contain polymerization initiators free radical initiators like methylethylketone peroxide cyclohexyl peroxide cumene hydroperoxide dibenzoyl peroxide etc and redoxy systems for generating free radicals well known in the art of polymerizing acrylate and methacrylate monomers could be such polymerization initiators compounds which generate radicals under ultraviolet or electron beam irradiation could also be considered as suitable polymerization initiators of the monomers of the present invention the various initiators could be used alone or in conjunction with each other in order to impart desired properties to the compounds of the present invention and to the properties of the resultant adhesive bond or polymer as well as for economic considerations further additives can be introduced they can be for example any of the known polymeric thickness and viscosity regulators rubbers plasticizers and tougheners compatibilizers thixotropic agents colourants deodorants or perfumes for example used in cyanoacrylate adhesives and in acrylic and methacrylic ester compositions and polymers the compounds of the present invention may also contain other monomers containing a reactive double bond a distinctive feature of the methacrylated or acrylated cyanoacetates of the present invention is that they are easily polymerizable by heat redoxy systems ultraviolet or electron beam irradiation a distinctive feature of the methacrylated or acrylated cyanoacetates of the present invention is that due to the presence of the.
