Abstract
An additive mixture containing (A) a binary system consisting of components (A1) and (A2), wherein (A1) is at least one organic cyclic phosphoric acid ester of the formula (I) wherein R0 is a direct bond, —S—, C3-C12cycloalkylidene or a group —C(X1)(X2)— with X1 and X2 independently of one another being hydrogen, C1-C18alkyl or C3-C12cycloalkyl; and the radicals R1 are identical and are C1-C18alkyl or C3-C12cycloalkyl unsubstituted or substituted by one, two or three C1-C4alkyl; and (A2) is at least one alkali or alkaline earth metal salt of a saturated or unsaturated aliphatic mono or dicarboxylic acid unsubstituted or substituted by —OH; and (B) a divalent metal alcoholate wherein the metal is Zn, Ca or Mg.
Claims21
An additive mixture containing
- (A) a binary system consisting of components (A1) and (A2), wherein
- (A1) is at least one organic cyclic phosphoric acid ester of formula (I)
- wherein
- R0 is a direct bond, —S—, C3-C12cycloalkylidene or a group —C(X1)(X2)— where X1 and X2 independently of one another are hydrogen, C1-C18alkyl or C3-C12cycloalkyl;
- and the radicals R1 are identical and are C1-C18alkyl or C3-C12cycloalkyl unsubstituted or substituted by one, two or three C1-C4alkyl;
- and
- (A2) is at least one alkali or alkaline earth metal salt of a saturated or unsaturated aliphatic mono or dicarboxylic acid unsubstituted or substituted by —OH;
- and
- (B) a divalent metal alcoholate wherein the metal is Zn, Ca or Mg.
A masterbatch containing a natural or synthetic polymer and 0.5% to 5%, relative to the weight of the natural or synthetic polymer, of components (A1) and (A2) where (A1) is at least one organic cyclic phosphoric acid ester of formula (I)
- wherein
- R0 is a direct bond, —S—, C3-C12cycloalkylidene or a group —C(X1)(X2)— where X1 and X2 independently of one another are hydrogen, C1-C18alkyl or C3-C12cycloalkyl;
- and the radicals R1 are identical and are C1-C18alkyl or C3-C12cycloalkyl unsubstituted or substituted by one, two or three C1-C4alkyl;
- and (A2) is at least one alkali or alkaline earth metal salt of a saturated or unsaturated aliphatic mono or dicarboxylic acid unsubstituted or substituted by —OH;
- characterized in that the molar ratio of components (A1):(A2) is 1:5 to 5:1;
- and with the proviso that the masterbatch does not contain a pigment.
