This invention relates to a process for purification of nanotube soot in a non-destructive and efficient method using a polymer having a coiling structure to extract nanotubes from their accompanying material without damage to their structure and with a high mass yield. Nanotube soot is added to a solvent which including a coiling polymer to form a solution. The solution is mixed with a nanotube composite suspension is formed with extraneous solid material such as amorphous carbon settling at th...

A composition consisting essentially of tris(hydroxymethyl)nitromethane and about an equal part of a mixture consisting of 4-(2-nitrobutyl)morpholine and 4,4-(2-ethyl-2-nitromethylene)dimorpholine in a ratio of about 3.5:1 respectively. The composition is useful as an antimicrobial.

There is described a composition comprising a substantially clear, sterile aqueous solution containing as active ingredient a therapeutically useful proportion of 1,3-bis(2-carboxy-chromon-5-yloxy)-propan-2-ol, or a pharmaceutically acceptable (e.g. the di-sodium) salt thereof, or of 5,5'-[[5,5'-(2-hydroxytrimethylene)dioxy]bis[4-oxo-4H-1-benzopyran-2-yl]]t etrazole, or a pharmaceutically acceptable (e.g. the di-sodium) salt thereof. The composition is indicated for the treatment of conditions o...

A composition comprising an end-capped aromatic carbonate polymer wherein the end-cap is of the structure ##STR1## wherein R is ##STR2## wherein R.sub.1 and R.sub.2 are the same or different and are alkyl of one to six carbon atoms, inclusive; cycloalkyl of four to seven carbon atoms, inclusive; phenyl; one to three alkyl substituted phenyl each alkyl having one to three carbon atoms, inclusive; and R.sub.1 and R.sub.2 taken together with the nitrogen to which they are attached form a ring of fo...

Thermoplastic molding composition of a polycarbonate and a linear low density polyethylene wherein a C.sub.4 -C.sub.7 alpha-olefin is the comonomer.

The invention relates to information carriers for optically readable information. The information carrier is built up from an actual carrier and a metal layer provided thereon. The actual carrier is manufactured from a polycarbonate resin consisting of a mixture of an aromatic polycarbonate, an epoxy compound and usual additives. The presence of an epoxy compound in the polycarbonate resin results in a better bonding between the metal layer and the polycarbonate resin. In order to be able to man...

A composition comprising an aromatic carbonate polymer in admixture with a mold release effective amount of a hydrogenated alpha-olefin oligomer fluid.

A composition comprising a compound of the formula wherein R is alkyl or alkenyl of eight to twenty two carbon atoms, inclusive or a mixture thereof and X is an alkali metal, alkaline earth metal, ammonium or substituted ammonium in combination with a soap or additional surfactant and moisture.
