摘要： The present invention describes preparation of nanocomposite particles and structures by polymerizing monomers onto a functional inorganic colloid comprising a polymerization initiation site. The polymerization process is preferably a controlled/living polymerization process, including but not limited to, atom transfer radical polymerization and stable free radical polymerization. The nanocomposite particles can self-organize in solution, on surfaces or in films forming nanocomposite structures. Tethered AB block nanocomposite particles bring size control, solubility control and control over micro- and macro-functionality to the particles. The process may be catalyzed by a transition metal complex which participates in a reversible redox cycle with at least one of the group and a compound having a radically transferable atom or group, to form a nanocomposite particle with a tethered polymer chain. The process may be continued to form tethered copolymer chain. The particle may be silicon based including, for example, silica, silicates and polysilsesquioxane. A nanocomposite structure may be formed by casting, depositing or forming the material including nanocomposite particles.

摘要： An improved process for free radical polymerization is produced making it possible to control the growth steps of a polymerization to produce homopolymers and copolymers, including block and graft copolymers. The process uses a long half-life radical initiators and compounds which have the structure of formula I ##STR1## wherein X is a group having at least one carbon atom and is such that the free radical X is capable of polymerizing the unsaturated monomer by free radical polymerization, and the radical functionality resides on the or one of the carbon atoms, R.sup.1, R.sup.2, R.sup.5 and R.sup.6 represent the same or different straight chain or branched substituted or unsubstituted alkyl groups of a chain length sufficient to provide steric hindrance and weakening of the O--X bond, and R.sup.3 and R.sup.4 represent the same or different, straight chain or branched, substituted alkyl groups or R.sup.3 CNCR.sup.4 may be part of a cyclic structure which may have fused with it another saturated or aromatic ring, the cyclic structure or aromatic ring being optionally substituted.
