RESIN COMPOSITION AND SHAPED PRODUCT
Provided are a polyamide/polyphenylene ether resin composition that has excellent fluidity, heat resistance, and surface impact strength while also having excellent repeated processability and a shaped product that includes this resin composition. The resin composition contains: (a) a polyamide; (b) a polyphenylene ether; (c) a compatibilizer for the (a) polyamide and the (b) polyphenylene ether; and (d) a polyhydric alcohol including at least two hydroxyl groups and having a number-average molecular weight (Mn) of less than 500. The content of the (d) polyhydric alcohol is 0.3 parts by mass to 5 parts by mass relative to 100 parts by mass, in total, of the (a) polyamide and the (b) polyphenylene ether. A ratio of terminal amino group concentration relative to terminal carboxyl group concentration (terminal amino group concentration/terminal carboxyl group concentration) in the (a) polyamide is 0.3 to 0.5. The (a) polyamide forms a continuous phase.

Fire-protection composition, multi-component system and use of the same
A fire protection composition contains a binder on the basis of an alkoxysilane-functionalized polymer and a liquid carbon supplier. The fire protection composition allows application in a simple and rapid manner of coatings having the layer thickness required for the particular fire resistance time, the layer thickness being reduced to a minimum while achieving a good fireproofing effect. The fire-protection composition is formulated as a multi-component system. The fire-protection composition is particularly suitable for fire protection, especially as a coating of construction elements such as steel carriers.
