ATRP from Silsesquioxane Initiators. In addition to silsesquioxanes with vinyl based monomeric units attached to corner silicon atoms, other species can be bonded to the cubes. One such example is the silsesquioxane shown in Scheme 7. Termed benzyl chloride functionalized polyhedral oligomeric silsesquioxane (benzyl chloride-POSS), the molecule contains seven cyclopentyl groups, which provide increased solubility in organic solvents, and one benzyl chloride moiety which can serve as an initiator for ATRP. Studies of such initiators may be of interest due to the bulky nature of the initiating species. Furthermore, the high temperature stability of the inorganic cubes may lend some interesting thermal properties to polymers initiated from it. 

Another strategy for moisture-adaptive shape-memory polymer preparation is to use water soluble segments as a soft segment to prepare SMPUs. Preparation is by polyhedral oligomeric silsesquioxane (POSS) molecules and poly(ethylene glycol) that act as the hydrophobic and hydrophilic groups. The POSS groups...
