Abstract
A polyurea or polyurea-urethane elastomer comprises a soft polymer segment and a hard polymer segment, wherein the hard polymer segment includes polyurea groups in combination with H-bond accepting chain extenders (HACEs) to reduce the flow temperature (T) while maintaining the excellent mechanical properties such that the resulting polyurea elatomer is rendered melt-processable.
