Abstract:
1. A fire retardant resin composition comprising a polyphenol compound and an inorganic microfine particle, wherein said polyphenol compound has such a structure that aromatic units each having at least one phenolic hydroxyl group are connected to one another through an organic unit containing two or more carbon atoms, wherein said organic trait containing two or more carbon atoms has a cyclic structure, and said inorganic microfine particle is a product of hydrolysis and condensation of an alkoxide compound and/or a carboxylic acid salt compound, wherein said microfine particle is a silica having not less than 0.001 nor more than 2.0 of an integral intensity ratio A Q 3 /A Q 4 obtainable by splitting a peak situated in the range of −120 to −80 ppm in 29 Si-DD/MAS-NMR spectrometry into a Q 3 silica component and a Q 4 silica component and has not more than 3.0 cal/g of exotherm per unit mass thereof as observed in differential scanning calorimetry and/or differential thermal analysis in an air stream at 100° C. to 400° C.
