Synthesis of polyurethane polymers via copper azide-alkyne click chemistry for coatings, adhesives, sealants and elastomer applications

Abstract

The present application is directed at the reaction product of an azide compound having two or more azide groups attached thereto and an alkyne compound having two or more alkyne groups attached thereto, wherein the azide and alkyne groups react in a 1,3-dipolar cyclo addition to form 1,4-disubstituted triazols and wherein the azide or alkyne compound or both include —O—(C═O)—NR— functional groups. The reaction products can be used as coatings, such as for flat roofs, sealants, adhesives and in elastomer applications. Methods for producing the reaction products as well as substrates including a coating of the reaction product are also disclosed.
