Abstract:
The present invention relates to coating compositions containing a polymeric or copolymeric levelling agent, which has been prepared by nitroxyl-mediated polymerisation. Further aspects are a process for the preparation of smooth surface coatings and the use of said polymer or copolymer as levelling agent in coating compositions. Yet another aspect are specific ethylenically unsaturated monomer compositions from which copolymers can be obtained by atom transfer radical polymerisation or nitroxyl mediated polymerisation, which copolymers are useful as levelling agents in coating compositions. Still another aspect is the use of poly-tert.-butyl acrylate or poly-tert.butylmethacrylate as a levelling agent in powder coating compositions.
Abstract:
Polymeric composites and methods of manufacturing polymeric composites are described. In one embodiment, a set of microcapsules containing a phase change material are mixed with a dispersing polymeric material to form a first blend. The dispersing polymeric material has a latent heat of at least 40 J/g and a transition temperature in the range of 0°C to 50°C. The first blend is processed to form a polymeric composite. The polymeric composite can be formed in a variety of shapes, such as pellets, fibers, flakes, sheets, films, rods, and so forth. The polymeric composite can be used as is or incorporated in various articles where a thermal regulating property is desired.

PROBLEM TO BE SOLVED: To provide an amino resin aqueous dispersion composition excellent in storage stability, mechanical stability and the like, a thermosetting aqueous coating material composition capable of forming a coating film excellent in coating film performance and the like, and a coating film-forming method. SOLUTION: The amino resin aqueous dispersion composition comprises a polyester resin having a specific monomer composition synthesized by using a monoepoxide compound as one constituting component. The thermosetting aqueous coating composition uses the amino resin aqueous dispersion composition. The multi-layer coating film-forming method uses the aqueous coating material composition.

Abstract:
PROBLEM TO BE SOLVED: To provide a thermoplastic polycarbonate resin composition free from brominated and/or chlorinated flame-retardant and having flame-retardance even in the form of a thin-walled article and provide a method for producing the composition. SOLUTION: The composition contains about 20 to about 90 wt.% polycarbonate resin, about ≤35 wt.% impact modifier, about 0.5 to about 30 wt.% polysiloxane-polycarbonate copolymer containing about 8 to about 30 wt.% polydimethylsiloxane unit or an equi-molar amount of other diorganosiloxane unit and about 0.5 to about 20 wt.% phosphorus-containing flame-retardant. The weight ratios are based on the total weight of the thermoplastic composition excluding the filler. A thermoplastic composition specimen having a thickness of 2.5 mm (±10%) and achieving the Class 5VA in UL94 is produced in one embodiment of the invention. Accordingly, the flame-retardance of this class can be achieved even in the form of a thin-walled specimen. COPYRIGHT: (C)2006,JPO&NCIPI
