Abstract
The butoxyl contents of cured urea‐formaldehyde‐butanol resin films have been determined by a modified Zeisel method, using a technique for film preparation whereby the film is obtained on a glass substrate under controlled conditions. The results show that such films have a high butoxyl content even after long periods of stoving, thus supporting the theory that under the conditions used in the preparation of the resin, the butanol reacts .with the methylol urea polymers to form relatively heat stable ethers.
