Abstract:The reaction between formaldehyde and proteins is of paramount importance in the development of protein plastics (2), coatings, sizes, adhesives, and fibers. It has been used in these industries as a so-called hardening process for many years.In processes that employ protein dispersions it has not oeen found possible to combine the formaldehyde with the protein before use, because they react with each other at a rather rapid rate to cause the formation of a precipitate. Therefore the formaldehyde treatment mus… Show more
“…The magnitude of this effect is illustrated by comparison of the curves for preparations P3 and P3-L. The maximum viscosity shown in the former was 10 poises and that in the latter, 1000 poises. Removal of the soluble, nonprotein material also raised the nitrogen content of the protein (P3) from 16.06 to 16.56% (P3-L).…”
