Abstract
Novel open-cell polymer foams are prepared from foamable polymer compositions comprising (a) an ethylenic ionomer which (1) is crosslinked by metal ions, (2) contains from 85 to 98.5 mol percent of ethylene polymerized therein and (3) has a crystallization initiating temperature, T, in DEG C satisfying the following Formula I: 102 – 3.02 (98.5 – A) > T > 102 – 9.29 (98.5 – A) I wherein A represents the ethylene content of said ionomer in mol percent, and (b) a suitable blowing agent. The resulting open-cell foam products are flexible and permit the passage of various fluid materials. They are useful as cushioning material for clothing, as packaging material for products requiring air permeability and as industrial filter media for anti-pollution applications, and the like.
