| abstract |
In order to improve the thermal stability of polycyanoacrylates, a combination of 2-cyanopentadienoic acid alkyl ester and alkylene-bis(2-pentadienoate), preferably in amounts of up to a total of 20 wt %, are added to cyanoacrylate adhesives based on monocyano-acrylic acid esters. The alkyl or alkylene group advantageously has between 2 and 4 carbon atoms. |
