Production of a copolymer monohydric phenol-dihydric phenol-aldehyde resin in the presence of an alkaline catalyst

Claim 1

THE METHOD OF PRODUCING A PERMANENTLY FUSIBLE COPOLYMER MONOHYDRIC PHENOL DIHYDRIC PHENOL-ALDEHYDE RESIN COMPRISING HEAT-FORMING IN THE PRESENCE OF AN ALKALINE CATALYST AN UNDEHYDRATED REACTION PRODUCT OF A MONOHYDRIC PHENOL SELECTED FROM THE GROUP CONSISTING OF PHENOL, CRESOL, XYLENOL AND CRESYLIC ACID, AND AN ALDEHYDE IN WHICH THE ALDEHYDE GROUP IS THE SOLE REACTIVE GROUP; SEPARATELY HEAT-FORMING AN UNDEHYDRATED PRIMARY REACTION PRODUCT OF A POLYHYDRIC PHENOL SELECTED FROM THE GROUP CONSISTING OF RESORCIN, CATECHOL, HYDROQUINONE, ORCIN AND PHLOROGLUCINOL, AND AN ALDEHYDE IN WHICH THE ALDEHYDE GROUP IS THE SOLE REACTIVE GROUP, MIXING SAID REACTION PRODUCTS, THE ALDEHYDE REACTANTS IN THE MIXTURE BEING IN THE RATIO TO THE TOTAL PHENOLIC CONTENTS OF THE MIXTURE TO PRODUCE A PERMANENTLY FUSIBLE RESIN, HEATING THE MIXTURE AND EFFECTING INTER-CONDENSATION OF THE PRIMARY MONOHYRIC PHENOL-ALDEHYDE CONDENSATION PRODUCT WITH THE PRIMARY POLYHYDRIC PHENOL-ALDEHYDE CONDENSATION PRODUCT AND PRODUCING A SUBSTANTIALLY HOMOGENEOUS UNDEHYDRATED LIQUID RESIN, AND DEHYDRATING AND FURTHER CONDENSING SAID LIQUID RESIN TO PRODUCE A SUBSTANTIALLY ANHYDROUS PERMANENTLY FUSIBLE COPOLYMER CONDENSATION PRODUCT.

Claim 2

THE METHOD OF PRODUCING A PERMANENTLY FUSIBLE COPOLYMER MONOHYDRIC PHENOL DIHYDRIC PHENOL-ALDEHYDE RESIN COMPRISING HEAT-FORMING IN THE PRESENCE OF AN ALKALINE CATALYST AN UNDEHYDRATED REACTION PRODUCT OF A MONOHYDRIC PHENOL SELECTED FROM THE GROUP CONSISTING OF PHENOL, CRESOL, XYLENOL AND CRESYLIC ACID, AND AN ALDEHYDE IN WHICH THE ALDEHYDE GROUP IS THE SOLE REACTIVE GROUP; SEPARATELY HEAT-FORMING AN UNDEHYDRATED PRIMARY REACTION PRODUCT OF A POLYHYDRIC PHENOL SELECTED FROM THE GROUP CONSISTING OF RESORCIN, CATECHOL, HYDROQUINONE, ORCIN AND PHLOROGLUCINOL, AND AN ALDEHYDE IN WHICH THE ALDEHYDE GROUP IS THE SOLE REACTIVE GROUP, MIXING SAID REACTION PRODUCTS, THE ALDEHYDE REACTANTS IN THE MIXTURE BEING IN THE RATIO TO THE TOTAL PHENOLIC CONTENTS OF THE MIXTURE TO PRODUCE A PERMANENTLY FUSIBLE RESIN, HEATING THE MIXTURE AND EFFECTING INTER-CONDENSATION OF THE PRIMARY MONOHYRIC PHENOL-ALDEHYDE CONDENSATION PRODUCT WITH THE PRIMARY POLYHYDRIC PHENOL-ALDEHYDE CONDENSATION PRODUCT AND PRODUCING A SUBSTANTIALLY HOMOGENEOUS UNDEHYDRATED LIQUID RESIN, AND DEHYDRATING AND FURTHER CONDENSING SAID LIQUID RESIN TO PRODUCE A SUBSTANTIALLY ANHYDROUS PERMANENTLY FUSIBLE COPOLYMER CONDENSATION PRODUCT.
