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. ## Claims ### Claim 1 A system comprising: a reactive component curable after exposure to a reaction initiator, wherein the reactive component comprises one or more members selected from the group consisting of a methylene malonate component, a methylene beta-ketoester component, a methylene beta-diketone component, and an oligomer or resin thereof; a first substrate formed of a plastic material and comprising the reaction initiator, the reaction initiator incorporated into the first substrate; and wherein the reactive component further comprises a carrier component; and wherein the plastic material and the reaction initiator are different. ### Claim 2 (depends on 1) The system according to claim 1, wherein the carrier component is partially soluble with the first substrate. ### Claim 3 (depends on 2) The system according to claim 2, wherein the carrier component comprises an additional reactive component. ### Claim 4 (depends on 1) The system according to claim 1, wherein the reactive component comprises one or more of a mono-functional and a multifunctional methylene malonate component. ### Claim 5 (depends on 1) The system according to claim 1, wherein the carrier component comprises one or more members selected from the group consisting of cyanoacrylates, epoxies, urethanes, polyurethanes, acrylics, and silicones. ### Claim 6 (depends on 1) The system according to claim 1, wherein the reactive component is cured. ### Claim 7 (depends on 1) A bonded article formed from the cured system of claim 1, further comprising a second substrate, wherein the reactive component is disposed between the first substrate and the second substrate. ### Claim 8 (depends on 7) The bonded article according to claim 7, wherein the second substrate is formed of a glass material, a metal material, a wood material, or another plastic material. ### Claim 9 (depends on 7) The bonded article according to claim 7, wherein the first substrate and the second substrate are formed of different materials. ### Claim 10 A method for bonding a first substrate formed of a plastic material to a second substrate, wherein the first substrate comprises a reaction initiator incorporated into the first substrate, the method comprising: a) providing a reactive component on the surface of the first substrate, the reactive component further comprising a carrier component; b) exposing the reactive component to the reaction initiator; and c) engaging at least a portion of the first substrate with the second substrate to create a bonding engagement; and wherein the reactive component comprises one or more members selected from the group consisting of a methylene malonate component, a methylene beta-ketoester component, a methylene beta-diketone component, and an oligomer or resin thereof; wherein the plastic material and the reaction initiator are different. ### Claim 11 A kit comprising: a first substrate formed of a plastic material and comprising a reaction initiator, the reaction initiator incorporated into the first substrate; a second substrate; and a plastic bonding adhesive composition comprising a reactive component effective to bond the first substrate to the second substrate upon exposure to the reaction initiator and a carrier component, wherein the reactive component comprises one or more members selected from the group consisting of a methylene malonate component, a methylene beta-ketoester component, a methylene beta-diketone component, and an oligomer or resin thereof; and wherein the plastic material and the reaction initiator are different.
