To an ice-cooled solution of Pd(PPh3)4 (0.04 mmol), PPh3 (0.08 mmol), and pyrrolidine (2 mmol) in acetonitrile (2.5 ml) was added a solution of poly(allyl methacrylate) (180 mg, 1.5 mmol of monomeric units) in acetonitrile (2.5 ml). After stirring at 60°C for 24 h, the mixture was poured into acetone and insoluble materials were isolated by centrifugation. The resulting precipitate was reacted with CH2N2 to convert it into PMMA. The conversion of allyl ester units into carboxylic acid units was approximately 90%, and it was necessary to repeat the reaction twice for the complete conversion. The appropriate conditions for this conversion reaction are now under examination to attain complete conversion through a single procedure.
