Micellization of block copolymers

Polymer-assisted fabrication of nanoparticles and nanocomposites

The contribution of anionic “living” polymerization techniques to macromolecular engineering has been decisive. The synthesis of well defined polymers of known structure, of low compositional heterogeneity, and of narrow molecular weight distribution are the major applications of anionic processes involving neither transfer nor spontaneous termination. It is necessary, however, to be aware of the limitations of these powerful methods, to avoid misgivings. If adequate systems are selected, and proper experimental conditions are chosen, a large variety of model macromolecules can be obtained anionically in good yields. Accurate characterization of these polymers is necessary to check for the efficiency of these methods.

Macromolecular engineering by anionic methods

Preparation and study of block copolymers with ordered structures

A polymer composition of low gas permeability. The composition includes an exfoliated organically-modified clay, butyl rubber, and a polymeric exfoliant. A method for producing the butyl composition by dry mixing the butyl rubber with the exfoliated clay is also provided.
