Abstract: Method to obtain methylene malonate and related monomers following a bis(hydroxymethyl) malonate pathway. A bis(hydroxymethyl) malonate intermediary is subsequently reacted (i.e., subjected to thermolysis) to provide a methylene malonate monomer species. A source of formaldehyde (e.g., formalin) is provided in the presence of a basic catalyst (e.g., calcium hydroxide), to which a malonate (e.g., diethyl malonate) is added under suitable reaction conditions to obtain the desired intermediary (e.g., dialkyl bis(hydroxymethyl) malonate). The intermediary is reacted (i.e., subjected to thermolysis) under suitable conditions in the presence of a suitable catalyst (e.g., a zeolite) to obtain a methylene malonate monomer. In an exemplary embodiment, the thermolysis reaction includes the addition of the bis(hydroxymethyl) malonate intermediary onto a heated catalyst. The reaction product is collected and purified. The disclosed methods may be performed in a continuous operation.

Abstract: Reactive composition includes a reactive component able to form an adhesive bond between two substrates, at least one of which comprises a plastic material. The substrate may include an initiator on or near the surface thereof. The initiator may be present in the plastic material inherently, by blending in an additive package, through injection molding, or other process. The reactive component may comprise a methylene malonate, a reactive multifunctional methylene, a methylene beta ketoester, a methylene beta diketone. A carrier component for the reactive component may be selected to interact with the plastic substrate to soften and/or penetrate the surface to be bonded. The surface of the plastic may be abraded or otherwise treated to expose the initiator. The reactive component, upon contact with a suitable initiator, is able to polymerize to form an interpenetrating polymer weld.

Abstract: An optical fiber is permanently routed easily, quickly, and unobtrusively at a customer premises using an inventive hand tool, without staples or other fasteners. The fiber has an adhesive outer coating that is activated as the fiber is applied by the tool on an exposed surface such as a wall, ceiling, molding, groove, or corner at the premises. When the activated coating hardens, the fiber is bonded to the surface on which it was applied, and the hardened coating also provides physical protection for the fiber. In the disclosed embodiment, the coated fiber is supplied on a spool that mounts on the tool, and the coating is activated by guiding the fiber as it unwinds from the spool through a chamber containing an activating substance. The fiber with the activated coating is then guided to an applicator wheel on the tool which applies the fiber to the surface.

Also provided are adhesive systems incorporating said encapsulated cure systems.

Abstract: The present invention provides improved methods for the chemical synthesis of methylene malonates using the Knovenagel synthesis reaction. The method of the invention provides for improved methylene malonates by significantly reducing or eliminating the formation of alternative and/or deleterious side products, significantly reducing or eliminating unwanted consumption of methylene malonates, and significantly reducing or eliminating the degradation of methylene malonates. These advantages result in methylene malonates, which upon recovery, are of higher quality, greater purity, improved yield and possess overall improved performance characteristics (e.g., improved cure speed, retention of cure speed, improved shelf-life and/or stability).
