description The invention relates to a dry cleaning solvent resistant hydrophilic urethane polymer having about 0.5 to 10 weight percent of a hindered phenolic antioxidant reacted into its structure. The invention also relates to a dry cleaning solvent resistant waterproof, moisture-vapor permeable material such as a laminate or a unitary sheet material. The unitary sheet material comprises a microporous polymeric matrix having pores comprising continuous passages extending through its thickness and opening into the opposite surfaces thereof, the passages being sufficiently filled with a moisture-vapor permeable, water-impermeable, hydrophilic material which comprises the polymer having the antioxidant reacted into its structure which prevents the passage of water and other liquids through the unitary sheet material while readily permitting moisture vapor transmission therethrough rendering the sheet material breathable. The unitary sheet material is made by causing a liquid composition comprising a hydrophilic material precursor to flow into the pores of the matrix, then causing the conversion thereof to solid hydrophilic material.
