Abstract
The present invention is directed to the formation of phenol alkylation polymers which release negligible phenol and formaldehyde emissions. The phenol aralkylation polymers of the present invention are derived from a phenolic monomer, at least one styrene derivative and an aryl diolefin. In addition to the phenolic monomer, styrene derivative and aryl diolefin, other reactants may be introduced to produce a product with particular properties.

A phenol aralkylation polymer produced by aralkylating a phenolic monomer with at least one styrene derivative in the presence of an acid catalyst to obtain an aralkylated phenol, then reacting the aralkylated phenol with an aryl diolefin to obtain the phenol aralkylation polymer, with the aralkylated phenol joined to the aryl diolefin primarily at the o position.
A process of producing a phenol aralkylation polymer comprising aralkylating a phenolic monomer with at least one styrene derivative in the presence of an acid catalyst to obtain an aralkylated phenol, then reacting the aralkylated phenol with an aryl diolefin to obtain the phenol aralkylation polymer, with the aralkylated phenol joined to the aryl diolefin primarily at the o position.
A phenol aralkylation polymer produced by aralkylating a phenolic monomer with at least one styrene derivative in the presence of an acid catalyst to obtain an aralkylated phenol, then reacting the aralkylated phenol with an aryl diolefin to obtain the phenol aralkylation polymer, wherein the phenolic monomer has three or four free reactive aromatic ring positions for reaction with said styrene derivative and said aryl diolefin, the mole ratio of aryl diolefin to said phenolic monomer is in the range of 0.2:1 to 1.1:1 and the aralkylation polymer exhibits a degree of styrenation in the range of 20 to 100%.
