Abstract

Mixtures of a phenol-aldehyde condensation product, hexamethylenetetramine and a low-boiling solvent therefor such as water are heated, with or without the addition of plasticizers or fluxing agents but without elimination of the solvent, in a mixer or on rolls at temperatures below 100 DEG C. until the boundary of the rubber-like state is reached and the material is prehardened to a considerable degree, and the resinous product obtained is moulded by the action of heat and pressure to obtain transparent articles.
