Title

Syntheses and characterization of 2,2'-biimidazole-containing macromolecules

Abstract

"The syntheses and characterization of new macromolecules formed by the reaction of 1,1'-dihydroxyethyl-2,2'-biimidazole(I) and tolylene diisocyanate has been investigated. The development of preparative techniques for (I) and the identification of applicable infrared, nuclear magnetic resonance, molecular weight, and thermal analysis methods for characterization of prepared polyurethanes were made. The nature of the products obtained were dependent on catalyst and solvent type, temperature and reaction time. Isolated polymers were characterized as aromatic polyurethanes having terminal hydroxyl and isocyanate functional groups with a high degree of cross-linking. Glass transition temperatures between 182 and 188ºC and number average molecular weights between 1600 and 3200 were observed. These polyurethanes exhibit thermoset properties and pyridine solution films cast on a metal substrate show good adhesion. These materials are expected to find application in coatings, adhesives, and as metal chelates"--Abstract, leaf ii.
