In the reaction of 2-[(organylthio)methyl]oxirans(I) with malonic, acetoacetic and cyanoacetic esters mixtures of 4- and 5-[(organylthio)methyl]-3-(methoxy-carbonyl-, acetyl-, cyano-)-4,5-dihydro-2(3H)-furanones (II)-(VII) are formed. The ratio of the isomers depends on the nature of the CH-acid. The reaction of 2-[(ethylthio)methyl]oxiran (Ia) with bis(butylsulfonyl)methane leads to a mixture of 3-(ethylthio)-1-[bis(butylsulfonyl)methyl]-propan-2-ol (XIa) and 3-(ethylthio)-2-[bis(butylsulfonyl)methyl]propan-1-ol (XIIa) in a 1:1 ratio. In the reaction of epoxides (I) with acetylacetone 4-[(organylthio)methyl]-2-methyl-2-acetonyl-1,3-dioxolanes (XIII) are formed.

The invention relates to isocyanate-free elastomer adhesives based on hybrid urethane-acrylate epoxies. The hybrid shows properties consistent for structural adhesives with excellent mechanical and thermal stability, and low read-through. The adhesives are suitable for use in industry, e.g., as adhesives for automotive applications.
