Abstract
A flame retardant which comprises an inorganic hydroxide and a carbodiimide-group-containing organic layer chemically bonded to the surface of the inorganic hydroxide. Examples of the carbodiimide-group-containing organic layer include a layer comprising a carbodiimide-group-containing compound represented by either of the following formulae. Due to the constitution, the flame retardant can be highly dispersed in a resin even when added in a high proportion and can give a molding inhibited from deteriorating in electrical properties, mechanical properties, etc. (1) (2)each independently represents hydrogen, halogeno, etc.; Z's each independently represents silicon or titanium; A represents an organic group having a valence of 2 or higher containing a bond derived from an isocyanate group; m and l each is an integer of 1-3, provided that m+1=4; and n is an integer of 1-100.]
