Polymerization of acetaldehyde and crotonaldehyde catalyzed by aliphatic tertiary amines

Abstract

Abstract Acetaldehyde was condensed with acetaldol using triethylamine as the catalyst. The reaction products of the branch‐chained type were found to predominate. Acetaldehyde was polymerized by trimethylamine, triethylamine, tri‐ n ‐propylamine, and tri‐ n ‐amylamine to resinous materials possessing desirable film‐forming properties. Crotonaldehyde was polymerized by triethylamine to a resin similar in all respects to the product of acetaldehyde produced under similar conditions.
