摘要:
The present invention relates to a process for the production of non-swellable phyllosilicate tactoids, comprising A) producing a synthetic smectite of the formula I in a high-temperature-melt synthesis [Mn/Valenz]inter[MImMIIo]oct [MIII4]tet X10Y2 (I) B) if the interlayer cation M does not already have a hydration enthalpy from −6282 to −406 [kJ/mol], exchanging the interlayer cation M with a cation having a hydration enthalpy from −6282 to −406 [kJ/mol] by a cation-exchange method, C) dispersing phyllosilicate in an aqueous system, and D) exchanging M with a cation having a hydration enthalpy from −405 to 0 [kJ/mol], by a cation-exchange method.

The present invention relates to nanoparticle-modified polyisocyanates which have been modified by a special siloxane unit and consequently have improved performance properties and also storage stabilities.
摘要:
The present invention relates to hybrid organic-inorganic polyisocyanates based on polyfunctional organosilanes, metal alkoxides and alkoxysilane-containing blocked polyisocyanates for the preparation of organic-inorganic coating compositions and adhesives.
摘要:
A thermoplastic molding composition that features improved thermal stability and a relatively low maximum rate of decomposition in the event of fire is disclosed. The composition contains an aromatic polycarbonate and/or polyester carbonate, and a modified layered compound, the modification with organic polymer by means of a solvent-free melt process. Optional additional components include an impact modifier, a thermoplastic (co)copolymer, and a phosphorus compound.
