초록 ▼

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°-180°C. for about 30-180 minutes prior to incorporating it in the cyanoacrylate.

대표청구항 ▼

The process for preparing an improved cyanoacrylate adhesive composition which comprises heating an acrylate polymer which has a reduced viscosity of substantially less than 5 and a content of free radical polymerization initiator of at least about 1% by weight, at a temperature of about 140°to about 180°centigrade and for about 30 to about 180 minutes and thereby increasing the reduced viscosity to at least about 5 and reducing the content of free radical polymerization initiator to less than about 0.5% by weight, said acrylate polymer having the repeating unit [Figure] wherein R1 is hydrogen, ethyl or methyl and R2 is a C1 to C4 alkyl or alkenyl group; and dissolving a quantity of the polymer so treated into a mixture of a monomeric ester of 2-cyanoacrylic acid and about 0.0005% to about 10% by weight of an inhibitor of anionic polymerization, the quantity of polymer being sufficient to produce a cyanoacrylate adhesive composition with a viscosity between about 500 and about 20,000 centipoise.
