Phenol aralkyistion polymers can be prepared by reaction among a phenolic monomer, at least one styrenic monomer and an aryl diolefin. A phenolic monomer can be 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 thereafter can be reacted with an aryl diolefin to obtain a phenol aralkylation polymer. Optionally, (though preferably) the phenol aralkylation polymer is further aralkylated with a second portion of at least one styrenic monomer. By employing specific catalyst concentrations, reactant concentrations, reaction temperatures, and reaction times, the formation of mono-functional and non-functional by-products is substantially reduced.

Process for reducing mono-functional and non-functional by-products during aralkylation of phenolics

Phenolic aralkylation polymers modified by esterification with fatty acids, transesterification with glyceride oils, or other modifications to reactive hydroxyl moieties to improve the characteristics and properties of coating systems in which the modified materials are incorporated. At least a portion of the hydroxyl moieties of the polyol is esterified or otherwise modified. The hydroxyl moieties include those that have been 'chain-extended,' if desired.

Alkyd and aralkyd derivatives of phenolic polymers

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.
