A method for preparing a poly(diorgano/organohydrogen)siloxane copolymer is provided. The method includes use of a vibrational spectroscopy technique.

Poly(diorgano/organohydrogen)siloxane copolymers

The present invention provides polymer composites, such as films, having dispersed therein quantum dots, wherein the polymer comprises (b) polymerized units of a first compound comprising from one to 6 thiol groups, the compound having a molecular weight from 300 to 20,000 and having at least one continuous acyclic hydrocarbyl chain of at least three carbon atoms, or, preferably, at least 5 carbon atoms; and (c) polymerized units of a second compound having a molecular weight from 100 to 750 and comprising at least two polymerizable vinyl groups as part of a (meth)acrylate ester group or attached directly to an aromatic ring and, wherein the molecular weight of the first compound minus the molecular weight of the second compound is at least 100. The polymer composites provide more stably dispersed and durable quantum dot compositions for use in, for example, display devices.

Processes for preparing N,N,N-trimethylethanolammonium hydroxide (choline hydroxide) and the choline hydroxide produced are described. These processes minimize the production of byproduct mono-ethoxylated and di-ethyoxylated choline in the product choline hydroxide. The processes generally include feeding ethylene oxide, trimethylamine, and water into a first reactor to create a first reactor product under temperature controlled conditions. The product of the first reactor is fed into a second reactor to form a second reactor product under uncontrolled, adiabatic, conditions. Finally, any unreacted trimethylamine in the second reactor product is removed to form a final product comprising choline hydroxide. Additional reactors can be used for the ethylene oxide and trimethylamine reaction.

Processes for the production of chlorinated alkanes are provided. The present processes comprise catalyzing the chlorination of a feedstream comprising one or more alkanes and/or alkenes with a catalyst system comprising one or more inorganic iodine salts and/or lower than conventional levels of elemental iodine and at least one Lewis acid. The processes are conducted in a nonaqueous media, and so, the one or more inorganic iodine salts are recoverable and/or reusable, in whole or in part.

Process for the production of chlorinated alkanes

Disclosed here are processes for preparing carbonized polymers (preferably carbon fibers), comprising sulfonating a polymer with a sulfonating agent that comprises SOdissolved in a solvent to form a sulfonated polymer; treating the sulfonated polymer with a heated solvent, wherein the temperature of the solvent is at least 95&#xb0; C.; and carbonizing the resulting product by heating it to a temperature of 500-3000&#xb0; C. Carbon fibers made according to these methods are also disclosed herein.

Processes for preparing carbon fibers using sulfur trioxide in a halogenated solvent

Processes for the production of chlorinated alkanes are provided. The present processes comprise catalyzing the addition of at least two chlorine atoms to an alkane and/or alkene with a catalyst system comprising one or more nonmetallic iodides and/or lower than conventional levels of elemental iodine and at least one Lewis acid. The present processes make use of sulfuryl chloride, or chlorine gas, as a chlorinating agent.
