Title: PHOSPHITES
Abstract:
The invention relates to phosphites of the formula (I) P (O-R1)x (O-R2)y (O-R3)z (O-R4)p where R1= an aromatic group with a C¿1?-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?2¿= an aromatic group with a C¿1?-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?3¿ = an aromatic group with a C¿1?-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?4¿= an aromatic group with substituents ortho, meta and para to the o atom which are different to those defined for R?1, R2 and R3¿, 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.
