A shape memory composition includes a high temperature ionomer having a glass transition temperature or a melting temperature of 100&#xb0; C. or greater and a modulus at room temperature of 1&#xd7;10Pa or greater, the high temperature ionomer including a polymer with ionic units either within the backbone of the polymer or pendant to the backbone or both. The shape memory composition includes crystalline or glassy domains of a low molecular weight non-polymeric compound dispersed in the high temperature ionomer and interacting the ionic units of the high temperature ionomer to form a secondary network characterized by being a reversible network in that it is compromised by the heating of the low molecular weight non-polymeric compound to change out of its crystalline or glassy phase.
