Abstract:
A phosphorus-containing compound represented by the following formula (I), (II) or (III): wherein Z1, Z2 and Z3 are the same or different, each representing a cycloalkane ring, a cycloalkene ring, a polycyclic aliphatic hydrocarbon ring or an aromatic hydrocarbon ring, in which these rings may have a substituent; R represents a halogen atom, a hydroxyl group, a carboxyl group, a halocarboxyl group, an alkyl group, an alkoxy group, an alkenyl group or an aryl group; A represents a polyvalent group corresponding to an alkane; Y1, Y2 and Y3are the same or different, each representing â€”Oâ€”, â€”Sâ€” or â€”NR1â€”wherein R1 represents a hydrogen atom or an alkyl group; k represents an integer of 1 to 6; m represents an integer of 0 to 2; n represents an integer of not less than 1; q represents an integer of 0 to 5; r represents 0 or 1; s represents an integer of 1 to 4; and provided that when Z1 is a cyclohexane ring, q is 0, and k is 1, factor r for A is 1; when Z1 is a cyclohexane ring, q is 0, and k is 2 to 6, at least one of plural factors r for A is 1; when Z1 is a benzene ring and k is 1, the factor r for A is 1; when Z1 is a benzene ring and k is 2 to 6, at least one of plural factors r for A is 1; and bis((1-oxo-2,6,7-trioxa-1-phosphabicyclo[2.2.2]-oct-4-yl)methyl) 2,5-dibromoterephthalate, 1,4-cyclohexanedimethanol bis(diaryl phosphate), (1-oxo-2,6,7-trioxa-1-phosphabicyclo[2.2.2]-oct-4-yl)methyl benzoate, (1-oxo-2,6,7-trioxa-1-phosphabicyclo[2.2.2]-oct-4-yl)methyl cyclohexanecarboxylate, tris(tricyclo[5.2.1.02,6]decane)phosphate, 2-carboxy-3-diphenylphosphoroxynorbornane, and 3-diphenylphosphoroxynorbornane are excluded.
