Alkyl substituted piperazines as chain extenders in polyurea elastomer systems |
abstract |
A polyurea elastomer is disclosed. The elastomer includes an isocyanate, an amine terminated polyoxyalkylene polyol, and a chain extender. The isocyanate is preferably a quasi-prepolymer of an isocyanate and a material selected from at least one polyol, a high molecular weight polyoxyalkyleneamine or a combination thereof. The chain extender includes at least an alkyl substituted piperazine. |
