The present invention relates to processes for making compatibilized high aspect ratio barrier additives and polymer compositions that comprise compatibilized high aspect ratio barrier additives. The invention also relates to compositions produced by these processes, and articles formed from polymer compositions of this invention. The barrier additives provide passive barriers to gas molecules such as oxygen and carbon dioxide minimizing transit of such molecules through sidewalls of polymer articles containing the barrier additives.

A porous filler for reducing the gas permeability of an elastomer composition, a process for producing the elastomer composition comprising the porous filler, and the elastomer composition itself. The porous filler is selected from surface-reacted calcium carbonate, precipitated hydromagnesite and mixtures thereof. The addition of the porous filler to the elastomer composition allows for reducing the gas permeability of the elastomer composition while retaining or improving the mechanical properties of the elastomer composition.

A polymeric composition for enhancing grip, including a modified solvent phase and a solid phase dispersed within the modified solvent phase. The modified solvent phase may include calcium-based gel, including calcium acetate particles partially dissolved in an alcoholic solution. The solid phase also includes a polymeric matrix and a plurality of desiccant particles encompassed by the polymeric matrix. The polymeric matrix includes polyvinyl acetate (PVAc) and a thickener.

A paint contains a zinc powder, a binding agent made of an organic resin, and an inorganic material that is water-soluble and exhibits alkalinity when being dissolved in water. The inorganic material can be, for example, one that provides a saturated aqueous solution having a pH of 12 or less. For example, the basic substance may be barium carbonate, barium hydrogen phosphate, beryllium carbonate, calcium carbonate, calcium hydrogen phosphate, calcium phosphate, lithium carbonate, lithium phosphate, magnesium carbonate, basic magnesium carbonate, magnesium hydroxide, magnesium oxide, or magnesium phosphate.
