摘要:
A thermally curing powder coating composition comprising a mixture of resins wherein at least one resin has a hydroxy number of less than 75 mg KOH/g, at least one resin has a hydroxy number of at least 75 mg KOH/g, and a curing agent for the resins. The powder coating composition is suited in particular for the decoration of substrates by transfer printing of an image. Very good results are found if the powder coating is used for the decoration of ceramic or glass substrates.
摘要:
The invention relates to a process for preparing a Ti (III) salt ether complex, such as TiCl 3 (THF) 3 , by reaction a corresponding Ti (IV) salt ether complex with a metal powder, with formation of a soluble metal chloride complex, in ether solvent. The Ti (III) salt ether complex that is prepared has a high purity, specifically a low aluminum content.

The invention relates to a polymeric optical amplifier doped with lanthanide ions, which are present in the amplifier in the form of a complex. The invention also relates to novel electrically neutral lanthanide complexes which can be applied with advantage in the above-described polymeric optical amplifiers. These complexes comprise host molecules which readily complex with the lanthanide and fully encapsulate it.
摘要:
A liquid stabilizer suitable for use in a vinyl chloride polymer comprising a liquid mixture of metal soap stabilizer, for example, a mixture of a mixed barium/zinc soap stabilizer and solubilized metal perchlorate, for example, a barium perchlorate. The liquid stabilizer is formed by combining a solubilized metal perchlorate and a liquid mixture of the metal soap stabilizer.

Nitrogen-containing polymers can be formed by the reaction of a polyketone, such as a copolymer of carbon monoxide and propylene, and an amino acid or derivative thereof, such as aspartic acid or glycine.
摘要:
A process and related apparatus for the continuous oxidation of a web of organic fiber. The web undergoes multiple parallel passes through an oxidizing chamber. Each pass enters and leaves the chamber through appropriate slots and upon leaving the chamber passes around a cooling cylinder external to the chamber which lowers the temperature of the web an appropriate amount prior to the next pass. The alternate passes are as close as conveniently possible to each other and the interior surfaces of the chamber highly reflective all of which enables the most efficient use of heat required by the system and maximization of the velocity of the web through the chamber.
摘要:
A process for the formation of pentaerythritol-based phosphorus heterocycles comprises the reaction of a pentaerythritol polyol, e.g., pentaerythritol, with a trivalent or pentavalent phosphorus compounds, e.g., a phosphorus oxytrihalide, a triorganophosphite, or a phosphorus trihalide, in an aryl phosphate solvent at elevated temperature.
