This invention relates to a process for producing cyanoacetates using a cyanoacetamide as a precursor.

Process for preparing cyanoacetates

This invention relates to a process for producing cyanoacetates using asparagine as a precursor to cyanoacetamide, a staring material to form the cyanoacetates.

Cyanoacrylate-containing compositions that include, in addition to the cyanoacrylate component, an anhydride and a toughening agent comprising a co-polymer of polyvinyl chloride and polyvinyl acetate are provided.

Cyanoacrylate compositions

This invention relates to a process for producing cyanoacetates involving contacting a salt of an alkyl, alkenyl, alkynyl or aryl formyl acetate with a hydroxyl amine acid under appropriate conditions and for a time sufficient to yield a cyanoacetate.

This invention relates to a process for producing cyanoacetates using aspartic acid as a precursor.

This invention relates to cyanoacrylate-containing compositions that include (a) a beta-alkoxy cyanoacrylate component, (b) a cyanoacrylate component selected from butyl cyanoacrylates, octyl cyanoacrylates, and combinations thereof; (c) a rubber toughening component (d) a surface modified component; and (e) an adhesion promoter. Cured products of the inventive cyanoacrylate compositions demonstrate improved toughness without an odor typically found with cyanoacrylate-containing compositions.

Curable cyanoacrylate compositions are reported that comprise cyanoacrylate and a thermoplastic polyurethane (TPU) components. Such compositions are toughened cyanoacrylate compositions exhibiting long term viscosity stability when stored for prolonged periods at room temperature (25&#xb0; C.). TPU components are reported having structural units in which at least one of the structural units has the formula &#x2014;O&#x2014;R&#x2014;O&#x2014;Ar&#x2014;O&#x2014;R&#x2014;O&#x2014;, wherein Ar is a C-Caromatic group with at least one aromatic ring; Ris a C-Calkyl group; and Ris a C-Calkyl group. The thermoplastic polyurethane (TPU) component may be present in the curable cyanoacrylate composition from about 1 wt % to about 40 wt %, for example from about 2 wt % to about 30 wt %, such from about 3 wt % to about 20 wt %, suitably from about 5 wt % to about 10 wt %, based on the total weight of the composition.

Toughened cyanoacrylate compositions

This invention relates to a process for producing electron deficient olefins, such as 2-cyanoacrylates, using an acid catalyzed Knoevenagel condensation reaction.

Process for preparing electron deficient olefins

This invention relates to a process for producing electron deficient olefin precursors, such as 2-cyanoacetates, using an acid catalyzed esterification reaction.

Process for preparing electron deficient olefin precursors

This invention relates to a process for preparing electron deficient olefins, such as 2-cyanoacrylates, using an acid catalyzed two-step process including an esterification reaction followed by a Knoevenagel condensation reaction.

This invention relates to a process for preparing electron deficient olefins, such as 2-cyanoacrylates, using an acid catalyzed two-step process including a transesterification reaction followed by a Knoevenagel condensation reaction.

This invention relates to a process for producing electron deficient olefin precursors, such as 2-cyanoacetates, using an acid catalyzed transesterification reaction.

This invention relates to cyanoacrylate-containing compositions, which when cured provide improved heat resistance.

The present invention relates to cured products of di- or poly-functional electron deficient olefins coated onto at least a portion of a surface of metal powders, such as metal powders used as appropriate in the formation of solder alloys, spheres and pastes.

Di- or poly-functional electron deficient olefins coated metal powders for solder paste

Two part cyanoacrylate/free radical curable adhesive systems, are provided.
