Media type: E-Article Title: Cationic ring‐opening polymerization of bicyclic amide acetals Contributor: Lu, Caixia; Odian, George Published: Wiley, 1994 Published in: Journal of Polymer Science Part A: Polymer Chemistry, 32 (1994) 12, Seite 2283-2290 Language: English DOI: 10.1002/pola.1994.080321210 ISSN: 0887-624X; 1099-0518 Keywords: Materials Chemistry ; Organic Chemistry ; Polymers and Plastics Origination: Footnote: Description: <jats:title>Abstract</jats:title><jats:p>Various bicyclic amide acetals were synthesized from the cycloaddition reactions of 2‐substituted‐2‐oxazolines with styrene oxide. Ring‐opening polymerization of the bicyclic amide acetals occurred upon heating in the presence of methyl tosylate. Characterization of the bicyclic amide acetals and their polymers was accomplished by NMR and elemental analysis. Vapor pressure osmometry showed the highest polymer molecular weight was only 2,400. The mechanisms for cycloaddition and polymerization are discussed. © 1994 John Wiley & Sons, Inc.</jats:p>
