Hydrophilic inorganic materials are provided with a hydrophobic surface by treatment with a metal glycolate compound having the formula: ##STR1## wherein: Me is Sn, Ti, Zr or Al;

Providing hydrophobic surfaces on hydrophilic inorganic materials with

1,3-Dicarbonyl compounds are provided having the formula: ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 are defined in the description as well as metal and organotin enolate salts thereof. The compounds are effective in enhancing the resistance to deterioration by heat and light of polyvinyl halide resins.

1,3-Dicarbonyl compounds and polyvinyl halide resin compositions

Stabilizer compositions and polyvinyl halide resin compositions containing 1,3-dicarbonyl compounds having the formula: ##STR1## as well as metal and organotin enolate salts thereof, effective in enhancing the resistance to deterioration by heat and light of polyvinyl halide resins.

Stabilizer compositions and polyvinyl halide resin compositions

A stabilizer composition is disclosed that enhances the resistance to deterioration upon heating of vinyl chloride polymers. The stabilizer composition comprises (A) a metal salt of a non-nitrogenous monocarboxylic acid or hydrocarbon-substituted phenol and (B) an aromatic carboxylic acid ester of a polyhydric alcohol having at least two alcoholic hydroxyl groups in a polyhydric alcohol aromatic carboxylic acid ester group. Vinyl chloride polymer compositions stabilized with the above disclosed stabilizer composition are also disclosed.

Aromatic carboxylic acid ester stabilizers for PVC resins

Improved clarity and resistance to deterioration on heating of polyvinyl fluoride and vinyl chloride polymers is obtained by employing a stabilizer composition consisting essentially of (A) a heterocyclic nitrogen compound having as part of a 5 or 6 membered heterocyclic ring the group ##STR1## in which R is hydrogen, aryl, or alkyl having 1 to 12 carbon atoms, and X is oxygen or sulfur, and (B) one or more 1,2-epoxides, organic phosphites, or stannous tin, zinc, magnesium, aluminum, potassium, sodium, calcium, strontium, or barium salts of non-nitrogenous monocarboxylic acids having from 6 to 24 carbon atoms or hydrocarbon-substituted phenols having from about 10 to about 30 carbon atoms.
