Abstract

275,678. Burmeister, R. Feb. 10, 1926. Moulding resins.-Plastic materials made from polyhydric phenols, particularly resorcinol, and paraformaldehyde or other solid polymer of formaldehyde, with or without the addition of fillers, are converted into moulded articles by a single pressing at 120-125‹ C. for a period of 2-5 minutes depending on the thickness of the article.
