Aza‐Michael silicone cure is accelerated by β‐hydroxyalkyl esters

Abstract The aza‐Michael reaction is proving to be a practical, catalyst free method by which a variety of polymers, including silicones, can be cured. However, its adoption may be compromised by slow cure rates; for many applications is it not practical to accelerate cure by heating. OH groups on the amine, acrylate partner or solvent are known to lead to accelerated rates of aza‐Michael reactions. The impact of the location of OH groups on …
