    Abstract: The invention relates to phosphites of the formula (I) P (O-R )x (O-R )y (O-R )z (O-R )p where R = an aromatic group with a C1-C18-alkyl substituent ortho to the O atom, or an aromatic substituent ortho to the O atom, or a fused aromatic system ortho to the O atom; R = an aromatic group with a C1-C18 alkyl substituent meta to the O atom, or an aromatic substituent meta to the O atom, or a fused aromatic system meta to the O atom, whereby the aromatic residue ortho to the O atom has a hydrogen atom; R = an aromatic group with a C1-C18 alkyl substituent para to the O atom, or an aromatic substituent para to the O atom, whereby the aromatic group ortho to the O atom has a hydrogen atom; R = an aromatic group with substituents ortho, meta and para to the o atom which are different to those defined for R , R and R , whereby the aromatic group ortho to the O atom has a hydrogen atom; x = 1 or 2; y, z and p, independent of each other = 0, 1 or 2 with the proviso, that x+y+z+p =3.
