By: 
Thomas H. Wicker
Newton H. Shearer

This invention relates to alpha-cyanoacrylate adhesive compositions and bonds formed therefrom. More particularly, our invention is concerned with adhesive formulations comprising monomeric esters of alpha-cyanoacrylic acid and vinyl aromatic compounds for bonding metallic or non-metallic surfaces to themselves or to each other and otherwise providing a superior bonded article.

By: 
Hanns Roland Misiak

This invention relates to toughened cyanoacrylate compositions which exhibit improved peel strengths and fixture speeds. The toughened cyanoacrylate compositions include a toughening agent comprising poly(vinychloride-co-vinyl acetate) and poly(methylmethacrytlate).

Shock Resistant Cyanoacrylate Compositions

WO2006048851
By: 
Patrick F. McDonnell
Ruth A. Kelly
Fergal W. Tierney
Robert J. Lambert

This invention relates to cyanoacrylate-containing compositions that exhibit at least one of improved shock resistance and bond strength, while demonstrating relative surface insensitivity with respect to establishing and maintaining fixture times that are on the order of comparable cyanoacrylate compositions without the added carboxylic acids, The compositions include, in addition to the cyanoacrylate component, certain carboxylic acids.

High Green Strength Emulsion rubbers by the use of Half-Esters of Unsaturated Dicarboxylic Acids

US4446282
By: 
George Jalics

The green strength of polymers produced by emulsion polymerization processes is improved through the use of carboxyl containing compounds. Specifically, the compounds are half esters of unsaturated dicarboxylic acids wherein the half ester moiety renders the carboxyl containing compound hydrophobic. As a result, carboxylic copolymers can be produced in emulsion polymerizations having a basic (pH.gtoreq.7.0) aqueous medium. Heretofore, use of carboxylic acids in emulsion polymerizations have been limited to acidic mediums.

Mixed Alpha-Cyanoacrylate Adhesive Compositions

US2776232
By: 
Newton H. Shearer
Harry W. Coover

This invention relates to adhesive compositions particularly adapted for forming flexible adhesive bonds and is particularly concerned with adhesive compositions comprising a mixture of at least two different esters of alpha-cyanoacrylic acid.

Toughened Cyanoacrylate Compositions Containing Elastomeric Rubbers

US4440910
By: 
John T. O'Connor

Disclosed are cyanoacrylate adhesive compositions containing elastomeric polymers as fillers. Preferred fillers are the acrylic rubbers. Filler concentration range from about 0.5-40% by weight of the composition. Beneficial results include improved toughness of the cured compositions, as measured by impact, peel and tensile strength properties, particularly after exposure elevated temperatures which would ordinarily severely degrade the adhesive strength.

Adhesive Composition

US4196271
By: 
Akira Yamada
Kaoru Kimura

An adhesive composition comprising a 2-cyanoacrylate and at least one member selected from the group consisting of substituted or unsubstituted aliphatic carboxylic acids having three or more carboxyl groups, anhydrides thereof, partial esters thereof, aromatic polycarboxylic acids having three or more carboxyl groups and anhydrides thereof. This composition has a high impact strength, is suitable for bonding metallic substrates to one another and is also excellent in resistance to heat, weather, and water.
