<p>Montacky, elastomeric shaped objects (e.g., pellets or filaments) comprising a normally tacky, uncured elastomer having an integral, porous coating of silicic or aluminic acid polymer can be prepared by bringing shaped bodies of a normally tacky, uncured elastomer latex into contact with an aqueous bath containing a soluble coagulating salt for the latex, and a silicic or aluminic acid polymer, and washing and drying the resulting coated shaped objects. The shaped objects are highly porous before washing and drying, and some porosity remains even after washing and drying.</p> |
