N-Allylcarbamoylmethyl cellulose (Allyl-CMC), which was prepared from the reaction of Su-CMC with an excess amount of allylamine, was crosslinked by UV-irradiation. In addition, the photocrosslinked Allyl-CMC film was swollen with water to form a hydrogel having a relatively high water-swelling property, e.g., the degree of swelling (ds) was ca. 360% for Allyl-CMC with the DS of 0.93.Springer Berlin / HeidelbergJournal Articleapplication/pdfhttp://hdl.handle.net/2115/5737https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/5737/1/PB56%282-3%29.pdf0887-624XPolymer Bulletin562-31371432006enginfo:doi/10.1007/s00289-005-0482-2The original publication is available at www.springerlink.comauthor
