    摘要： Hydrophobic polyurethane polymers which may be useful in making synthetic leathers comprising at least two immediately consecutive repeating units according to Formula I: (—OC(O)N—)nA-NC(O)O-L(M)-  (I) wherein n is 1 or 2, A represents the residue of an organic di- or tri-isocyanate compound, L represents a hydrocarbon group that optionally contains one or more catenary or non-catenary hetero-atoms, and M represents an oligomer comprising 2-12 (meth)acrylate units. The polyurethane polymers may additionally comprise end group(s) according to the formula -L′M wherein L′ represents a hydrocarbon group that may contain one or more catenary or non-catenary hetero-atoms. In some embodiments, M is according to Formula III: wherein Q is hydrogen or methyl, p is an integer between 2 and 12 inclusive, and Z is a hydrocarbon group which may optionally be substituted.

    摘要： A stretchable coated fabric is treated for water repellency with a fluorinated water repellent that comprises a copolymer containing a perfluoroalkyl group with six or less carbon atoms (C6 fluorinated water repellent). The use of no C8 fluorinated water repellents that contain perfluorooctanoic acid, perfluorooctane sulfonate, and the like makes the fabric exerts no influence on the environment. And the fluorinated water repellent has a toluene repellency of 100 seconds or longer; a synthetic resin solution applied to at least one side of the stretchable fiber fabric has a thixotropic index at 23° C. in a range from 1.4 to 2.0; and the synthetic resin has a 100% modulus of 5 kgf/cm2 or greater. This prevents the synthetic resin from leaking to the back side and allows formation of a resin coating film that has good film forming properties.
