## ionomer cluster

https://doi.org/10.1351/goldbook.IT07215
Ionic aggregate, in a polymer matrix of low @P04710@, formed through interactions of @I03229@ multiplets.
Notes:
1. The @M03955@ of the polymer segments surrounding the multiplets is reduced relative to that of bulk material. With increasing ion content, the @N04262@ of the @I03229@ multiplets increases, leading to overlapping of the restricted @M03955@ regions around the multiplets and the formation of clusters.
2. Typically, an @I03229@ exhibits two @G02640@ temperatures ($$T_{\text{g}}$$), one for the non-polar matrix and the other for clusters.
