Abstract: A method of preparing an .alpha.-cyanoacrylate ester of a desired alcohol includes the steps ofpreparing a compound which is an .alpha.-selenoaryl-.alpha.-cyanopropionate ester of the desired alcohol,oxidizing said .alpha.-selenoaryl-.alpha.-cyanopropionate ester to the corresponding selenoxide,eliminating arylselenic acid from the selenoxide to produce said .alpha.-cyanoacrylate ester, andseparating said .alpha.-cyanoacrylate ester from the selenic acid.At temperatures of about 0.degree. C. or higher, the elimination step occurs concurrently with the oxidizing step using a peroxide or ozone oxidizing agent. The desired cyanoacrylate ester is obtained in good yield and very high purity. The method can be used to prepare difficult to synthesize plural functional cyanoacrylate monomers and mono- cyanoacrylate monomers regardless of alcohol chain length.

Abstract: The invention comprises a curable acrylic ester formulation which contains a maleimide thermal additive which is essentially miscible in conventional acrylic monomers. The formulation comprises a substantially solvent free adhesive formulation comprising:a) an acrylic functional maleimide compound of the formula: ##STR1## where the R.sub.1 groups are independently H or C.sub.1 -C.sub.3 alkyl, R.sup.2 is lower alkylene and R.sup.3 is defined as for R.sup.1 ;b) at least one acrylate or methacrylate monomer or prepolymer compound other than a compound as defined in a); and,c) an effective amount of an anaerobic or thermal free radical initiator.

Abstract: Bis-maleimide compounds of the formula: ##STR1## where R' is an alkenylene or alkylene group; the R" groups are independently hydrocarbon or halohydrocarbon groups; and n is an integer, are hydrolytically stable compounds which may be thermally cured, or co-cured with other radically cureable monomers, to provide crosslinked polymer with good thermal properties. Compounds of the formula where n is above about 9 can be used as additives for radically cureable silicone formulations.
