Stabilizer combination, useful for halogen containing polymers comprises at least one aminoalcohol and a halogen containing salt of an oxy-acid and/or at least one aminocrotonate compound.

摘要

A stabilizer combination comprises at least one aminoalcohol and a halogen containing salt of an oxy-acid and/or at least one aminocrotonate compound. A stabilizer combination (I) comprises at least one aminoalcohol and a halogen containing salt of an oxy-acid and/or at least one compound of formula (1). n = 1-100,000; R1,R2,R4,R5 = H, 1-44C alkyl, optonally substituted and/or unsaturated, 6-44C cycloalkyl, optionally substituted and/or unsaturated, 6-44C aryl or 7-44C aralkyl, optionally substituted or R1 is a 2-44C acyl, optionally substituted or R1 and R2 form an aromatic or heterocyclic system; R3 = H, 1-44C alkyl, alkylene, oxyalkyl, oxyalkylene, mercaptoalkyl, mercaptoalkylene, aminoalkylor aminoalkylene, optionally substittuted and/or unsaturated or 6-44C aryl or arylene or an ether or thioether having 1-20 O- and/or S-atoms or a polymer bonded in O, S, NH, NR4 or CH2C(O) to the structural element within brackets or R3 is bonded to R1 to form a 4-24C heterocyclic ring system, optionally unsaturated and/or substituted Independent claims are included for : (i) a polymer composition containing the stabilizer composition (I); (ii) molded articles containing the polymer composition; and (iii) a process for the stabilization of a halogen containing polymer, optionally mixed with other polymers by addition of the stabilizer composition (I).
