The invention relates to a mixture of stabilisers for the stabilisation of chlorinated polymers, comprising at least a) a sulphate ester salt and/or a sulphonate salt of formula (I): [R(O)sSO3]tM and b) an alkanolamine of formu la (II), where M = alkali, earth alkali, lanthanide (Cer) or aluminium cation, t = metal cation valence of 1, 2 or 3; s = 0 or 1, R = C1-C22 alkyl, phenyl, C 7- C10 phenylalkyl, C7-C24 alkylphenyl, x = 1, 2 or 3; y = 1, 2, 3, 4, 5 or 6; n = 1 - 10; R1,R2 independently = H, C1-C22 alkyl, -[-(CHR3a)y-CHR3b-O-]n-H, - [- (CHR3a)y-CHR3b-O-]n-CO-R4, C2-C20 alkenyl, C2-C18 acyl, C4-C8 cycloalkyl, optionally substituted at the .szlig.-position by OH, C6-C10 aryl, C7-C10 alkaryl or C7-C10 aralkyl, or when x = 1, R1 and R2 together with the N can form a closed 4-10 membered ring of carbon atoms with optionally up to 2 heteroatoms, or when x = 2, R1 also = C2-C18 alkylene, optionally substitute d at both .szlig.-carbon atoms with OH and/or interrupted by 1 or more O atoms and/or 1 or more NR2 groups, or dihydroxysubstituted tetrahydrodicyclopentadienylene, dihydroxysubstituted ethylcyclohexanylene, dihydroxysubstituted 4,4'-(bisphenol-A-dipropylether)ylene, isophoronylene, dimethylcyclohexanylene, dicyclohexylmethanylene or 3,3'- dmethyldicyclohexylmethanylene and when x = 3, R1 also = trihydroxysubstitut ed (tri-N-propylisocyanurate)triyl, R3a,R3b independently = C1-C22 alkyl, C2-C6 alkenyl, C6-C10 aryl, H or CH2-X-R5, where X = O, S, -O-CO- or -CO-O-; R4 = C1- C18 alkyl/alkenyl or phenyl and R5 = H, C1-C22 alkyl, C2-C22 alkenyl or C6-C 10 aryl.
