Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
87 words
THE METHOD OF MAKING AN INTERNALLY PLASTICIZED THERMOSETTING RESIN, WHICH COMPRISES HEATING WITH A STAGE OF CURING AT A TEMPERATURE OF 85 TO 95*C. FOR AT LEAST 6 HOURS A MIXTURE CONSISTING OF MONO-HYDROXYBENZENE AND A PARA MONO-ALKYL PHENOL IN WHICH THE ALKYL SIDE GROUP IS OF 8 TO 12 CARBON ATOMS, THE RATIO OF ALKYL PHENOL TO HYDROXYBENZENE BEING 0.5 TO 1.25, WITH AN ALDEHYDE IN AMOUNT OF 0.85 TO 2.35 MOLES PER MOLE OF THE MIXED PHENOLS, AND IN THE PRESENCE OF A CONDENSING AGENT.
