Abstract: The process consists of a two-step synthesis of ?-methylene-?-butyrolactones from the parent ?-butyrolactones in a single vessel by a process wherein an alkoxide base, a formate ester, and a lactone are reacted using a solvent mixture comprising an aromatic hydrocarbon, and optionally, secondary and/or tertiary alcohols in the first step. By-products that lower overall yield and are difficult to separate from the desired product are eliminated or substantially reduced using a neutralizing agent to convert residual alkoxide to a weak base and/or distillation. In the second stage, a formaldehyde source is introduced to form the final a-methylene lactone. The ?-methylene-?-butyrolactones are useful as monomers for preparing highTg homopolymers or copolymers by various methods for applications with the desirable characteristics of low volatility, increased polymer rigidity, improved optical, and/or thermal stability properties.

Abstract: An acrylic adhesive composition is provided comprising a free-radical polymerizable monomer, an initiation system and a co-accelerator that enhances the reactivity of the initiation system by increasing the reaction rate between the oxidizing agent and the reducing agent. The free radical-polymerizable monomer preferably comprises methyl methacrylate (MMA), the initiator system preferably comprises N,N-diisopropanol-p-toluidine (DIIPT) and benzoyl peroxide (BPO), and the co-accelerator preferably comprises 1,4-diazabicyclo[2.2.2]octane (or triethylene diamine (TDA)).

Abstract: Acrylic adhesion promoters having an improved property such as cohesive failure are produced from a monocyclic anhydride of phosphonic acid containing multiple carboxylic acids that is subsequently reacted with a hydroxyalkyl methacrylate. The adhesion promoters are useful in bonding to metal substrates including oily metal substrates.

Abstract: Polyhydroxyl functional compounds that contain an all hydrocarbon backbone, wherein all of the hydroxyl groups are bonded to a primary carbon atom, are prepared through the reaction of an alpha, omega-terminal diol having a total of from about 6 to about 42 carbon atoms terminated with a mono-ol having a total of from about 4 to about 42 carbon atoms. The polyols can be used as additives in hydrocarbon oils, drilling fluids, industrial and automotive lubricating fluids, dispersants, engine lubricants, greases, coatings, adhesives, and also in magnetorheological fluids to improve various properties such as dispersion, wear protection, reduction of friction, high temperature stability, and improved aging.

Abstract: A powder adhesive comprising a primary rubber bonding polymer and a thermosetting component, and a method for bonding elastomers to metals employing the same. By adding a thermosetting component to a powdered adhesive, the adhesive may be applied to a substrate, sintered and thermoset to provide a sweep resistant adhesive film on the substrate, which may subsequently be bonded to an elastomer. Without a thermosetting component, the adhesive is at risk to re-melt or otherwise soften during a heated elastomer molding operation which in turn could cause the adhesive material to sweep off the substrate.

Abstract: A powder adhesive composition for bonding an elastomer to metals or other rigid substrates comprising a powdered film forming polymer having a liquefaction temperature above room temperature and is capable of forming rubber tearing bonds between an elastomer and a substrate. The adhesive composition is shelf stable and free flowing at room temperature to allow for ease of storage and electrostatic spray application, yet melts or flows at elevated temperatures to form a film on a coated substrate prior to elastomer bonding.

Abstract: An adhesive composition is provided which is capable of bonding to metallic surfaces which are contaminated with oil or oily residue. An adhesion improving additive is added to the base adhesive/coating composition which enables the adhesive to achieve better bonding to oily substrates. Addition of the adhesion improving additive improves the adhesion of adhesives, sealants, and coatings to the oily substrates used in the automotive and industrial markets. The an adhesion improving additive is an aliphatic molecule of at least 8 carbon atoms or having an aliphatic end group or side chain of least 6 carbon atoms, and wherein the adhesion improving additive comprises a boiling point of at least 30° C.
