Abstract: Amino plastics and phenolic plastics are produced by making a precondensate solution in an extruder and then compounding with additives and degassing in a partly- filled second extruder. A process for the production of amino plastics and phenolic plastics comprises (a) making a precondensate solution in an extruder and then (b) transferring the solution (16) continuously to another extruder (20) in which the inlet zone (E) and degassing zone (G) are kept partly filled, and in which it is compounded with additives, degassed, and extruded to a semi-finished or final product.
