Abstract: Phosphite of formula P(A)(B)C where at least one of A, B or C is of formula (I). and the others may be 1-60C oxyaryl or oxy (cycloalkyl provided the total amt. of C atoms in A, B and C is u0-180, R1-4 are 0-3H atoms, phenyl, naphthyl or 5-12C cycloalkyl these gps. opt. substd. by 1-9C alkyl or 1-4Cl atoms, 1-60C alkyl opt. substd. by phenyl, 7-10C alkylphenyl or 5-12C cycloalkyl all of these gps. opt. contg. (thio)ether carboxylic acid ester, epoxy C=C or halogen gps. and/or R2 and R3 together form an (un)satd. 3-10C alkylene chain opt. substd. by alkyl or aryl gp. with the proviso that the total amt. of C atoms in R1-4, is 4-60, R5 is -CH2CH2- or -CH2CH(OH)CH2-; X is O, S or SO2 and m is 1-10. The phosphites are heat and light stabilisers for polymers and may form synergic mixts. with e.g. phenols or sulphides for polypropylene. They have improved weather and hydrolysis resistance, possess less tendency to bleed, form scale on processing machinery or fish eyes in moulding and they are odourless. Phosphites with an >1 pref. >3 have antistatic properties as well. They may be used for (chlorinated) polyolefins, polyesters, polyamides, polyethers, polyurethanes, polyacrylonitrile, polysiloxanes etc.

Abstract: of the disclosure: In the stabilization of halogen-containing polymer compositions metal salts of acid boric acid esters are used as costabilizers besides the known primary stabilizers, whereby an excellent stabilization effect is obtained without affecting the color of the polymer.

Abstract: Halogen-containing polymers are heat-stabilized by physiologically unobjectionable mixtures consisting of 10 to 70% by weight of an aluminum salt, 10 to 80% by weight of a calcium salt and 10 to 70% by weight of a zinc salt of an aliphatic mono- or dicarboxylic acid or an aromatic mono-, di-, or tricarboxylic acid.

Abstract: of the disclosure: The present invention is related to novel phosphites, their use as stabilizers for organic polymers, furthermore to stabilizer compositions containing those novel phosphites as well as the organic polymers being stabilized therewith. The novel phosphites have a good stabilization effect, especially in combination with known stabilizers, and they are substantially stable against hydrolytical influence. Their volatility and tendency to exudation are very weak.
