This invention relates to modified alpha-cyanoacrylates adhesive compositions and is particularly concerned with alpha-cyanoacrylate compositions containing up to 50% of a polymerizable neutral vinyl monomer admixed with monomeric alpha-cyanoacrylate ester.

This invention related to adhesive compositions containing certain esters of alpha-cyanoacrylic acid and to methods for their use.

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.

My invention relates to improvements in blowing agents for the manufacture of porous rubber and plastic articles. Foamed articles of plastics or rubber are prepared by various means including solution of nitrogen under high pressures and subsequent release of pressure. A simpler method is to incorporated in the rubber or plastic composition a suitable chemical agent which, on heating to vulcanization or molding temperatures, releases large quantities of gas and thus causes foaming of the composition.
