PREPARATION OF PHENOLIC POLYMERS BY ARALKYLATION REACTIONS
The present invention is directed to a method for preparing phenol aralkylation polymers by reaction among a phenolic monomer, a styrenic monomer and an aryl diolefin, characterized by the absence of a solvent, wherein a phenolic monomer is initially aralkylated in the presence of an acid catalyst w...
