Mixed acetals arereadily obtained from the corresponding alcohols and ethyl vinyl ether, using an acidiccatalyst. Conventional etherification involving a primary halide was also examined. Themonomers thus obtained were successfully polymerised by a free radical mechanism,yielding unbranched linear and soluble polymers with pending sucrose moieties, and someof their physical properties were determined.<\/jats:p>","DOI":"10.3390\/molecules13040762","type":"journal-article","created":{"date-parts":[[2008,10,2]],"date-time":"2008-10-02T12:45:09Z","timestamp":1222951509000},"page":"762-770","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Novel Unsaturated Sucrose Ethers and Their Application as Monomers"],"prefix":"10.3390","volume":"13","author":[{"given":"Carina C.","family":"Crucho","sequence":"first","affiliation":[{"name":"REQUIMTE, Departamento de Qu\u00edmica - FCT, Universidade Nova de Lisboa, Quinta da Torre, 2829-516 Caparica, Portugal"}]},{"given":"Krasimira T.","family":"Petrova","sequence":"additional","affiliation":[{"name":"REQUIMTE, Departamento de Qu\u00edmica - FCT, Universidade Nova de Lisboa, Quinta da Torre, 2829-516 Caparica, Portugal"}]},{"given":"Rui C.","family":"Pinto","sequence":"additional","affiliation":[{"name":"REQUIMTE, Departamento de Qu\u00edmica - FCT, Universidade Nova de Lisboa, Quinta da Torre, 2829-516 Caparica, Portugal"}]},{"given":"Maria T.","family":"Barros","sequence":"additional","affiliation":[{"name":"REQUIMTE, Departamento de Qu\u00edmica - FCT, Universidade Nova de Lisboa, Quinta da Torre, 2829-516 Caparica, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2008,3,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"65","DOI":"10.1016\/j.crci.2004.02.002","article-title":"Carbohydrates as green raw materials for the chemical industry","volume":"7","author":"Lichtenthaler","year":"2004","journal-title":"Compt.
