Poly uses, potential

Ultraviolet Stability of PMMA—PVdF Poly blends. The potential ultraviolet resistance of this polyblend was of considerable interest. Let us first consider what is known of the photochemical stability of the components. 

Thermal analysis as well as particle morphology and redispersion of precrosslinked poly(organosiloxane) microparticles proved to be promising with regard to an application as potential toughening agents. This caused us to investigate the principal suitability of silicone particles as modifiers for thermoplastic polymers. 

Enzymatic reactions have been tested in SCFs on a pilot plant scale, and a detailed analysis of potential technical solutions and costs is given in Chapter 4.9. Finally, the synthesis of energetic materials has been suggested to be performed in liquid or supercritical CO2. The Indian Head Division of the US Naval Surface Warfare Center is now constructing a pilot plant with a 100 L vessel for the synthesis of such energetics as MTV (magnesium/Teflon/ Viton) and poly-3-nitratoraethy 1-3-methyl oxetane [190,191]. 

Polymer-embedded gold nanoparticles have been extensively studied [1]. Because of unique physical characteristics, gold-polymer nanocomposites are potentially useful for a number of advanced functional applications, especially in the optical and photonic fields. In particular, these materials can be used as light-stable color filters [2], polarizers [3, 4], ultra-low refractive index materials [5], nonlinear optical devices [6], optical sensors [7], and so on. However, still limited are the chemical routes that allow us to obtain monodispersed thiol-derivatized gold nanoparticles with controlled size to be embedded into poly-... 

The possibility of easy functionalization of the hydroxyl group of the initial polymers by various complexing groups, which potentially allows us to synthesize a variety of metal complex catalysts for different reactions. Methods of modifying the hydroxyl group of poly(ethylene oxide)s and ethylene oxide-propylene oxide block copolymers are very numerous and are described in a number of reviews [25-30]. Moreover, terminally modified... 

PCBs and PCDDs. In Diarylide Yellow manufacture, the use of formate buffer to enhance pigment transparency for offset ink was discontinued in the nineteen seventies, when it was realized that polychlorinated biphenyls were being produced as an undesirable by-product of the coupling reaction. In Phthalocyanine Blue crude synthesis, the commonly used solvent, trichlorobenzene, was also discontinued in the US, as a potential source of poly-chlorinated biphenyls. More recently, use of chloranil, manufactured from chlorinated phenols, has been discontinued in the synthesis of dioxazine violet crude and sulfonated dioxazine acid dyes, so as to minimize by-product formation of polychlorinated dibenzodioxins and dibenzofurans (PCDDs/PCDFs). A new grade ofhigh purity chloranil is now produced from hydroquinone for dye and pigment manufacture. 

Recently we succeeded in preparing rather large quantities of a primary amine-bearing aliphatic polyester derived from L- and DL-serine, namely poly(amino serinate) or PAS. This polyamine is a potential carrier for oligonucleotides and DNA fragments. It enabled us to make bioresorbable polyelectrolyte complexes where drugs could be easily entrapped for sometime . 

The major value of the new Structure-Activity Relationship presented and developed by us [19] for (poly)alkene + OH reactions resides in its inherent predictive potential regarding the detailed primary-product distributions of such reactions. This is especially useful for quantitative assessments of the various possible OH-initiated degradation pathways of biogenic VOC, of which there is such a diversity and multitude that one can realistically hope to perform detailed experimental studies on only a few of them.

Our synthesis of polyaniline was a modification of works of Honzl and Moore and involved the polycondensation of para-phenylenediamine with 2,5-dihydroxy-1,4-dihydroterephthalic acid (DHDHTA). The reaction afforded a blue-black product in a crude yield of 90%s. The achievement of such a high yield encouraged us to determine the scope of this synthesis for the preparation of a potentially large group of "polyanilines" (poly-a-phenyleneamines) resulting from the condensation of essentially any aromatic diamine and DHDHTA as shown below.
