Abstract

The invention relates to a method for producing a stabilizer composition for a polymer. 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, and the carboxylic acid is reacted with the metal compound in a continuous manner in an extruder (1) while discharging the resulting reaction water out of the extruder (1). The invention further relates to a correspondingly produced stabilizer composition.

Abstract

Particulate solid heat stabilizer compositions for vinyl halide polymers are provided having about 30% to 90% by weight hydrotalcite particles represented by a sigmoidal curve on a cartesian coordinate plot of zeta potential (mV) versus pH. The curve has negative zeta potential values balanced against positive zeta potential values over a pH range and an inflection point between a pH of about 3 about 6 representing the isoelectric point (IEP) between said negative and positive zeta potential values. The stabilizer compositions are essentially free flowing, storage stable, and processable upon mixing components of the composition for blending with a vinyl halide polymer in effective amounts to confer heat stabilizing effectiveness upon said polymer.
