Waterproof breathable material for polyurethane resin and polyurethane resin composition

摘要

An object of the present invention, there is provided to provide a moisture-permeable, waterproof and washing resistance either to the moisture permeable waterproof material for a polyurethane resin excellent also in, moisture-permeable waterproof material for the polyurethane resin of the present invention have the general formula ( It is represented by one) and at least one compound containing active hydrogen (S1) and by reacting an active hydrogen component comprising an oxyethylene-containing polymer diol (a1) (A1) with the organic polyisocyanate component (B) The resulting that it is characterized. [In general formula ^(1), X 1 represents a residue obtained by removing the c-number of active hydrogen from the m-valent active hydrogen-containing compound; c represents an integer satisfying 1 ≦ c ≦ m; m is 1 to 20 of an integer; X ² represents a residue formed by removing one active hydrogen from an active hydrogen-containing compound, a plurality of X ² may be the same or different, different X ² and X ¹ are the same respectively may be the; Y represents a residue obtained by removing all the carboxyl groups from a trivalent or higher aromatic polycarboxylic acids, aromatic ring Y consists of carbon atoms, substituted except carboxyl group on its carbon atom groups and / or halogen atoms are bonded to have carbon atoms may, but at least one well is not bonded substituent; a represents an integer of 1 or more, b represents an integer of 0 or more, 2 met ≦ a + b ≦ d-2; d is the number of hydrogen atoms bonded to a carbon atom constituting an aromatic ring in the case of replacing all the substituents containing a carboxyl group of the aromatic polycarboxylic acid to a hydrogen atom, namely It represents the number of the substitutable sites on the aromatic ring. ]
