Ring-opening polymerization of polyarylates

Abstract

146-150A series of new macrocyclic arylates have been efficiently synthesized and unambiguously characterized by a combination of GPC, MS (FAB) and 1<span style="font-size:11.0pt;font-family: " calibri","sans-serif";mso-ascii-theme-font:minor-latin;mso-fareast-font-family:="" "times="" new="" roman";mso-fareast-theme-font:minor-fareast;mso-hansi-theme-font:="" minor-latin;mso-bidi-font-family:arial;mso-ansi-language:en-us;mso-fareast-language:="" en-us;mso-bidi-language:ar-sa"="">H <span style="font-size:11.0pt; font-family:" calibri","sans-serif";mso-ascii-theme-font:minor-latin;mso-fareast-font-family:="" "times="" new="" roman";mso-fareast-theme-font:minor-fareast;mso-hansi-theme-font:="" minor-latin;mso-bidi-font-family:"times="" roman";mso-ansi-language:en-us;="" mso-fareast-language:en-us;mso-bidi-language:ar-sa"="">NMR. These macrocycles undergo facile ring opening polymerization in the presence of anionic initiators to give high molecular weight polyarylates.</span
