1. Functional nanocomposites prepared by self-assembly and polymerization of diacetylene surfactants and silicic acid

Author

Yi Yang, Mengcheng Lu, Yunfeng Lu, Jinman Huang, Haddah, Raid, Xomeritakis, George, Nanguo Liu, Malanoski, Anthony P., Sturmayr, Dietmar, Hongyou Fan, Sasaki, Darryl Y.l, Assink, Roger A., Shelnutt, John A., Swol, Frank van, Lopez, Gabriel P., Burns, Alan R., and Brinker, C. Jeffrey

Abstract

The nanostructured inorganic host altered the diacetylene polymerization behavior, and the resulting nanocomposites show unique thermo-, mechano-, and solvate-chromic properties, and polymerization of the incorporated surfactants resulted in polydiacetylene (PDA)/silica nanocomposites. The nanostructured inorganic framework serves to protect, stabilize, and orient the polymer, mediate its performance, and provide sufficient mechanical and chemical stability to enable integration of conjugated polymers into devices and microsystems.

Subjects
Lactic acid -- Chemical properties, Polymers -- Structure, Polymers -- Chemical properties, Addition polymerization -- Methods, Polymerization -- Methods, Chemistry
Abstract

The synthesis of chiral aluminum and yttrium alpoxides and their applications for lactide polymerization is reported. Homochiral (R)-4 was found to exhibit excellent stereocontrol in a range of polymerization.

3. Preparation of semiconductor nanoparticle-polymer composites by direct reverse micelle polymerization using polymerisable surfactants

Author

Hirai, Takayuki, Watanabe, Tatsufumi, and Komasawa, Isao

Subjects
Addition polymerization -- Methods, Polymerization -- Methods, Polymers -- Chemical properties, Chemicals, plastics and rubber industries
Abstract

The nanoparticles were incorporated successfuly into the polymerized CVDAV (PCV) and retained their size and quantum size effect. The synthesized CVDAC is soluble in polar solvents such as methanol, ethanol, acetone and chloroform and also in aromatic solvents such as benzene and toluene but is soluble in paraffinic solvents.

4. Alpha-aldehyde terminally functional methacrylic polymers from living radical polymerization: Application in protein conjugation 'Pegylation'

Author

Tao, Lei, Mantorani, Giuseppe, Lecolley, Francois, and Haddleton, David M.

Subjects
Polymers -- Chemical properties, Copper -- Chemical properties, Addition polymerization -- Methods, Polymerization -- Methods, Chemistry
Abstract

The synthesis of new alpha-aldehyde-terminated poly(methoxyPEG)methacrylates obtained through Cu(I) mediated living radical polymerization and their application for the conjugation of proteins using lysozyme as a model is presented. This method appears to be general and may be extended to many proteins and most of the monomers amenable to metal-catalyzed living radical polymerization.

5. Bulk synthesis of polypyrrole nanofibers by a seeding approach

Author

Xinyu Zhang and Manohar, Sanjeev K.

Subjects
Addition polymerization -- Methods, Polymerization -- Methods, Polymers -- Chemical properties, Pyrrole -- Chemical properties, Chemistry
Abstract

A rapid and convenient seeding method to chemically synthesize bulk quantities of microns-long, 60-90 nm thick nanofibers of polypyrrole is described. The findings have a potential to be leveraged beyond conducting polymers to embrace the broad class of precipitation polymerization reactions.

6. An extraordinarily rapid polymerization of vinylpentaflourocyclopropane: Highly stereo- and regioselective synthesis of unsaturated fluoropolymers

Author

Zhen-Yu Yang

Subjects
Addition polymerization -- Methods, Polymerization -- Methods, Polymers -- Chemical properties, Cyclopropane compounds -- Structure, Cyclopropane compounds -- Chemical properties, Chemistry
Abstract

Mainly the saturated fluoropolymers have great amount of thermal and chemical consistency, low surface power, increased insulating capability, minimal refractive index and dual electric consistency. Moreover, the monomer vinylpentafluorocyclopropane is planned and synthesized in such a manner that it creates polymers consisting of polarized double bonds, which cannot be entered via radical polymerization of fluorinated dienes or dehydrofluorination of additional fluoropolymers.
