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.

Abstract: The present disclosure is directed to a thermoplastic polymer for additive manufacturing, wherein the thermoplastic polymer is derived from a chlorinated monomer unit, wherein the thermoplastic polymer has a melt flow rae (MFR) suitable for additive manufacturing.

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.
