Stabiliser combinations for chlorinated polymers

摘要

A stabilizer combination comprises at least one uracil compound and at least one polyol and/or disaccharide alcohol. A stabilizer combination (I) comprises: (A) at least one uracil compound of formula (1); and (B) at least one polyol and/or disaccharide alcohol. R1, R2 = 1-12C alkyl, 3-6C alkenyl optionally substituted by one to three 1-4C alkyl, 1-4C alkoxy, 5-8C cycloalkyl or OH or Cl substituted 5-8C cycloalkyl, phenyl optionally substituted with one to three 1-4C alkyl, alkoxy or 5-8C cycloalkyl or OH or Cl substituted 7-9C phenyl alkyl or H; Y = O or S. Independent claims are included for: (i) a composition comprising a chlorine containing polymer and the combination (I); (ii) a process for the stabilization of a chlorine containing polymer by addition of the combination (I).
