실험 절차

A mixture of furfuryl alcohol and a urea-formaldehyde resin is prepared. Phenol and furfuryl alcohol and paraformaldehyde are heated together to produce a phenol formaldehyde pre-condensate admixture with furfuryl alcohol. The urea-formaldehyde-furfuryl alcohol precondensate and phenol-formaldehyde-furfuryl alcohol admixture are mixed with poly furfuryl alcohol and heated at a temperature of about 120°-160° F. for several hours until a viscous liquid pre-polymer admixture is obtained.
