✦ Synopsis

The irradiation dose was 200 kGy at a dose rate of 48.6 kGy h À1 . After irradiation, the polymer was isolated by removal of any remaining monomer with methanol. The polymer yield was determined by gravimetric analysis.

NMR, IR, and UV spectra were recorded on a JEOL JMN A-400, JASCO Herschel FT-IR-430, and JASCO V-550 spectrometer, respectively. The powder X-ray diffraction data were collected with a Rigaku RINT-2100 diffractometer with monochromated Cu Ka radiation (l = 1.5418 , 30 kV, 20 mA, scan speed 1 deg min À1 ). The thermogravimetric/differential thermal analysis measurements were carried out using a Seiko TG/DTA 6200 in a nitrogen stream at a heating rate of 10 8C min À1 .
