A transparent solid glue, in mass percentage comprises: 10.0%-50.0% of glycerol, 5.0%-20.0% of propylene glycol, 5.0%-30.0% of sticky substance, 1.0%-10.0% of stearic acid, 0-5.0% of vegetable oil, 0.5%-5.0% of protopine, 0.1%-5.0 of excipient, 0.1%-0.5% of preservative, and 5.0%-70.0% of deionized water, wherein the excipient is C.sub.12-16 saturated or unsaturated fatty acid salt. The prepared transparent solid glue has high initial viscosity; and the drying time is controllable so that the gluing position of the objects to be glued can be adjusted according to actual requirements, which is convenient to use, and the glue exhibits strong adhesion after completely drying. Meanwhile, the addition of protopine causes the pH of the solid glue to be between 10.49-10.99, and accordingly the solid glue is an environmentally friendly solid glue. Within a temperature range from −5° C. to 40° C., this solid glue is widely applicable to gluing paper, wood pieces, photographic paper, paperboards and etc.

The present teachings are directed at 1,1-disubstituted alkene monomers (e.g., methylene beta-ketoester monomers), methods for producing the same, polymerizable compositions including a methylene beta-ketoester monomer, and polymers, compositions and products formed therefrom. The monomer preferably is a high purity monomer. In the method for producing the methylene beta-ketoesters of the invention, a beta-ketoester may be reacted with a source of formaldehyde. The methylene beta-ketoester monomers may be used in monomer-based products (e.g., inks, adhesives, coatings, sealants or reactive molding) and polymer-based products (e.g., fibers, films, sheets, medical polymers, composite polymers and surfactants).

Optically clear adhesive or coating layers can be prepared by preparing a curable mixture, coating the curable mixture to form a layer, partially curing the curable mixture, drying the coated layer, and fully curing the curable mixture. The curable mixture may also be partially cured and then coated, dried and fully cured. The curable mixture includes two free radically polymerizable monomer compositions that are relatively incompatible and a transient compatibilizer, such as a solvent. Polymers of the two monomer compositions, if polymerized separately and blended, form phase separated domains. The curable mixture provides for adhesive or coating layers that are optically clear.

Free radical-curing (meth)acrylate resins contain stabilizers and acidic adhesion promoters. The (meth)acrylate resins are characterized by particularly high storage stability, even at relatively high temperatures, and a concomitant increase in the activity of the accelerator present in the (meth)acrylate resin. The special stabilizers increase the storage stability, give rise to a rapid cure rate, and make the curing properties insensitive to the acidic adhesion promoters present alongside them. This makes it possible for very good adhesion to a wide variety of materials and thus a broader field of use.
