Title: Improvements in or relating to the manufacture of phenolic resins
IPC: C08G8/08
Filed: 1961-02-28
Abstract: Phenolic resins are formed by heating an aqueous mixture of one or more phenols, formaldehyde and a bivalent metal borate until an intermediate which will thermoset when heated at 150 DEG C. is formed, and continuing the heating with distillation of water at a temperature below 150 DEG  until a thermoplastic product is formed. Suitable phenols are monohydroxybenzene, cresols, xylenols, resorcinol, bisphenol, bisphenol A and phloroglucinol.  Suitable borates are those of Zn, Mn and Ni.  The products may be cured with addition of a formaldehyde donor, e.g. hexamethylene tetramine. They are useful for moulding, or after solution in alcohol as phenolic varnishes.  In examples phenol, aqueous formaldehyde and 3Zn0.2B2O3 were refluxed at a pH of 4.4 at 100-103 DEG C. for 2 hours.  Then heating was continued with distillation until the temperature reached 125 DEG C. and the product was thermosetting at 150 DEG C.  Continued heating at 125 DEG C. for 1 hour yielded a solid and grindable when cool resin which was thermoplastic.
