Method of making polyepoxide modified oxyalkylation derivatives, said derivatives obtained in turn by oxyalkylation of phenol-aldehyde resins and product resulting therefrom

Claim 1

A TWO-STEP MANUFACTURING METHOD, THE FIRST STEP INVOLVING AN INTERMEDIATE (ABA) WHICH, IN TURN, REPRESENTS THE REACTION PRODUCTS OF (A) AN OXYALKYLATED PHENOLALDEHYDE RESIN CONTAINING A PLURALITY OF ACTIVE HYDROGEN ATOMS, AND (B) A PHENOLIC POLYEPOXIDE CONTAINING AT LEAST TWO 1,2-EPOXY RINGS FREE FROM REACTIVE FUNCTIONAL GROUPS OTHER THAN 1,2-EPOXY AND HYDROXYL GROUPS, AND COGENERICALLY ASSOCIATED COMPOUNDS FORMED IN THE PREPARATION OF SAID POLYEPOXIDES; SAID EPOXIDES BEING MONOMERS AND LOW MOLAL POLYMERS NOT EXCEEDING THE TETRAMERS; SAID EXPOXIDES BEING SELECTED FROM THE CLASS CONSISTING OF (A) COMPOUNDS WHERE THE PHENOLIC NUCLEI ARE DIRECTLY JOINED WITHOUT AN INTERVENING BRIDGE RADICAL, AND (B) COMPOUNDS CONTAINING A RADICAL IN WHICH TWO PHENOLIC NUCLEI ARE JOINED BY A DIVALENT RADICAL SELECTED FROM THE CLASS CONSISTING OF KETONE RESIDUES FORMED BY THE ELIMINATION OF THE KETONIC OXYGEN ATOM, AND ALDEHYDE RESIDUES OBTAINED BY THE ELIMINATION OF THE ALDEHYDE OXYGEN ATOM, THE DIVALENT RADICAL
