Amphiphilic latex nanoparticles comprise a core and shell, The core contains hydrophobic vinylic grafted copolymer and hydrophobic vinylic homopolymer, and the shell to which the hydrophobic vinylic polymer is grafted is a hydrophilic, nitrogen-containing polymer. Typically the particles are made by a process which involves generating radicals on the nitrogen atoms of said hydrophilic polymer, and then initiating free-radical polymerisation of said vinylic monomer, hydrophobic vinylic polymer separating to form latexes of highly monodispersed core-shell particles with the hydrophobic polymer as the core and said hydrophilic polymer as the shell.

New polynuclear aromatic diamines, such as 2,2′-di-(p-aminophenoxy)-biphenyl, a process for their manufacture and their use as polycondensation components for the manufacture of polyamide, polyamide-imide and polyimide polymers are described. The polymers obtained with the aromatic diamines according to the invention are readily soluble and can also be processed from the melt and are distinguished by good thermal, electrical and/or mechanical properties.

A class of soluble poly(aryletherimides) (PAEIs) having flexible backbones, useful in the manufacture of polymeric optical films are disclosed. The poly(aryletherimides) are dissolved in organic solvents, such as ketones and ketone solvent mixtures and coated on variety of substrates such as triacetyl cellulose (TAC), to form clear thin-layer films which display negative birefringence. The thin films can serve as compensation layers in liquid crystal displays (LCDs), and can be combined with other types of optical films, such as polarizers, brightness enhancement films, or other compensation films, to from multi-layered films that are especially useful in the manufacture of LCDs.

The manufacture of polyetherquinoxalines may be accomplished by polymerization of quinoxaline and related monomers with a bisphenol under aromatic nucleophilic substitution reaction conditions. A method of manufacture includes contacting a substituted or unsubstituted quinoxaline having replaceable groups at the 2,3 positions with a bisphenol or a bisphenol derivative under aromatic nucleophilic substitution reaction conditions. The resulting polyetherquinoxalines contain quinoxaline groups joined by ether linkages at the 2 and 3 positions of the quinoxaline groups. In one example, the polyetherquinoxaline has a formula represented as.

The present invention relates to conjugated polymers and a method for their synthesis. Furthermore, the present invention relates to electro-synthesis methods for producing polymers that include the use of at least one Lewis acid and at least one proton trap to form organic conjugated polymers having elevated refractive indices. In one embodiment, the present invention relates to an organic polymer having an elevated refractive index, the organic polymer formed by a process comprising the steps of: providing a solution of unsaturated organic monomer units and at least one acidic component; impeding saturation of the unsaturated organic-monomer units by at least one protic element in the solution; and polymerizing the unsaturated organic monomer units to form a conjugated organic polymer having a refractive index of at least about 2. 3 for electromagnetic energy having a wavelength of about 700 nm.
