Size‐dependent changes of transition temperatures in polymers are shown to derive from two principal sources: the effect of surface energy (or interfacial tension) and the role of the interface in the mixing of foreign material with the system. The formal elements and physical insight necessary for a description of the influence of domain size on the two main polymer transitions, the glass transition and melting, are discussed in some detail.
