In some variations, this disclosure provides compositions for reducing fluid permeability through a polymer membrane, the composition comprising a polymer (e.g., bromobutyl rubber) and mineral particles (e.g., kaolin particles) including fine particles with particle sizes between about 0.05 μm and about 1 μm and coarse particles with particle sizes between about 3 μm and about 20 μm. Applications for these improved-barrier polymers include tire innerliners, paint and paper coatings, films, adhesives, liners, paints, and hoses, for example. Methods of making and use these polymers are also disclosed. |
