ABSTRACT:
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 with a first portion of at least one styrenic monomer to obtain an aralkylated phenol, the aralkylated phenol is reacted with an aryl diolefin to obtain a phenol aralkylation polymer, and then optionally, (though preferably) the phenol aralkylation polymer is further aralkylated with a second portion of at least one styrenic monomer.
