This invention relates to the thermal stabilization of halogen-containing polymer compositions, more particularly, this invention relates to a poly(vinyl chloride) (PVC) or a chlorinated polyvinyl chloride (cPVC) composition comprising a methyl tin stabilizer and at least one salt of a polyacid material such as a polycarboxylic acid, a phosphoric acid, or a boric acid.

Stabilized polymer compositions

A composite material containing a thermoplastic material and a non-functional aromatic end group-containing polymer is disclosed. Also disclosed are methods of making and use the composite materials.

Composite material containing non-functional aromatic end group-containing polymer

Disclosed herein are low Shore A Hardness thermoplastic vulcanizate compositions having high Rebound values. In at least one exemplary embodiment, the compositions include a dispersed at least partially vulcanized rubber component; a thermoplastic component; and process oil; wherein the weight ratio of the thermoplastic component to the rubber component ranges from 80:20 to 15:85; and the thermoplastic component comprises more than 80 wt % of a polypropylene (preferably a random propylene copolymer) having a melting point less than about 105&#xb0; C. The compositions can be used in molded products, consumer goods and the like.
