Resins from Formaldehyde. (Part LVII). Reaction of m-Xylene-Formaldehyde Resin with Polyacenaphthylene

Urea-formaldehyde Adhesive Resins*

Approximately 1 million metric tons of urea-formal-dehyde resin are produced annually. More than 70% of this urea-formaldehyde resin is used by the forest products in-*This information was written and prepared by a U.S. Government employee on official time and it is, therefore, in the public domain and not subject to copyright.

Occupational asthma due to formaldehyde resin dust with and without reaction to formaldehyde gas.

We report the cases of three subjects who developed asthma after being exposed to formaldehyde dust or gas. For two subjects, specific bronchial provocation tests with formaldehyde gas did not cause significant bronchoconstriction, whereas exposure to formaldehyde resin dust did. One subject experienced asthmatic reaction after being exposed to formaldehyde resin dust and gas. These findings su...

Resorcinol-Formaldehyde (R-F) Resin

The formaldehyde-hemoglobin reaction.

It is now generally accepted that formaldehyde reacts initially with amino groups of proteins to form methylolamines, which then react more slowly to form methylene bridges between the amino groups and such other groups as the amide group and the phenol& indole, and imidazole rings (Fraenkel-Conrat and Olcott (1) ; Alexander et al. (2)). Some of these bridges are intermolecular. The present pot...
