KONTINUERLIG FRAMSTAELLNING AV FENOL-FORMALDEHYDHARTS OCH AV DENNA FRAMSTAELLDA LAMINATER

摘要

A process is disclosed whereby water-soluble phenol-formaldehyde resins are produced from molten phenol and particulate paraformaldehyde in the presence of an alkaline catalyst by reacting in a coil container at a temperature ranging from about 90 DEG C. to 120 DEG C. Apparatus for conducting the reaction and decorative laminates produced from the resultant resin are also disclosed.
