Abstract
A method for producing a stabilizer composition for a polymer and a stabilizer composition produced by the method. At least one carboxylic acid is reacted with at least one metal compound, such as at least one metal hydroxide and/or at least one metal oxide and/or at least one metal carbonate, thereby forming a metal carboxylate of the carboxylic acid. The reaction of the carboxylic acid with the metal compound is carried out in a continuous manner in an extruder while reaction water being formed is discharged out of the extruder.

A method for producing a stabilizer composition for a polymer, the method comprising:
- reacting in an extruder at least one carboxylic acid with at least one metal compound in a continuous manner, thereby forming a metal carboxylate of the carboxylic acid and reaction water in a continuous manner, and
- discharging the reaction water being formed out of the extruder through openings arranged on an outer side of the extruder along the flow of material prior to where the stabilizer composition exits the extruder.
