## Abstract

An adhesive composition includes a photoinitiator and an acrylate-cyanoacrylate monomer. The acrylate-cyanoacrylate monomer includes at least one acrylate functional group to enable photo-curing of the adhesive composition and at least one cyanoacrylate functional group to enable latent curing of the adhesive composition.

## Claims

### Claim 1

A process of forming an acrylate-cyanoacrylate monomer, the process comprising:
forming a mixture that includes a polyol, acrylic acid, and 2-cyanoacrylic acid; and
initiating a transesterification reaction to form an acrylate-cyanoacrylate monomer having at least one acrylate functional group and at least one cyanoacrylate functional group.

### Claim 2 (depends on 1)

The process of claim 1, wherein the polyol includes trimethylolpropane.

### Claim 3 (depends on 1)

The process of claim 1, wherein the polyol includes di(trimethylolpropane).

### Claim 4 (depends on 1)

The process of claim 1, wherein the polyol includes pentaerythritol.
