Abstract
Stable cyanoacrylate adhesive compositions having viscosities greater than about 200 centipoise are prepared by incorporating therein, as a thickening agent, a soluble acrylic polymer having a reduced viscosity of about 5 or greater, and a content of free radical polymerization initiator less than 1% by weight. These properties are obtained by subjecting the thickening agent to temperatures of about 140.degree.-180.degree. C. for about 30-180 minutes prior to incorporating it in the cyanoacrylate.
