    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 micro-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: Improved processes have been developed for atom (or group) transfer radical polymerization (ATRP). In one improvement, the ATRP process involves polymerizing in the presence of a (partially) free radical-deactivating amount of the corresponding reduced or oxidized transition metal compound. In a further improvement, the ATRP process involves polymerizing in a homogeneous system or in the presence of a solubilized initiating/catalytic system. The present invention also concerns end-functional, site-specific functional and telechelic homopolymers and copolymers; block, random, graft, alternating and tapered (or "gradient") copolymers which may have certain properties or a certain novel structure; star, comb and "hyperbranched" polymers and copolymers; multi-functional hyperbranched, end-functional polymers; cross-linked polymers and gels; water-soluble polymers and hydrogels (e.g., a copolymer prepared by radical copolymerization of a water-soluble monomer and a divinyl monomer); and an ATRP process using water as a medium.
