Resorcinol → p-Toluenesulfonic acid

Participants

Reaction Steps

An antireflective composition was prepared by dissolving together 0.6682 g of the polymer of Example 1, 0.1177 g of the trimeric condensate of resorcinol and diethylol-p-cresol (plasticizer), 0.0990 g of Powderlink 1174 crosslinker (from Cytec Industries), an acid crosslinking catalyst consisting of 0.009 g of p-toluenesulphonic acid monohydrate (Aldrich), 0.0072 g of FC 430 surfactant (3M Corp.) and 30.96 g of proylene glycol methyl ether alcohol solvent. After dissolution, the solution was filtered through a polypropylene filter with a 0.2 um pore size.
