  • Hydrophobic polyurethane resins
    Patent number: 11015012
    Abstract: 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.
