| Abstract: | We describe the synthesis of three anthracene–methacrylate monomers [9‐methacryloxymethyl‐10‐methyl anthracene ( 4 ), 9‐methacryloxyethyloxymethyl‐10‐methyl anthracene ( 5 ), and 9‐methacryloxy‐10‐methyl anthracene ( 6 )] as well as their emulsion copolymers containing butylacrylate. When films prepared from latex dispersions containing 4 or 5 were heated, the anthracene (An) group was cleaved from the polymer at temperatures above 120 °C. Lower temperatures induced this reaction when strong acids were present. In 4 and 5 , the polymerizable group is connected to the An ring via a 9‐CH2O? linkage. The cleavage reaction requires more stringent conditions when the connection involves a benzylic ether ( 5 ) instead of a benzylic ester. Polymers prepared from 6 , with an An? O? bond, were stable for 1 h at 150 °C in the presence of 0.5 wt % p‐toluene sulfonic acid. © 2001 John Wiley & Sons, Inc. J Polym Sci A: Polym Chem 39: 1495–1504, 2001 |
