Polycarbonate comprising at least one phosphoric group, obtained by reacting a hydroxy-group-containing polycarbonate with a phosphorus compound (I), is new. Polycarbonate comprising at least one phosphoric group, obtained by reacting a hydroxy-group-containing polycarbonate with a phosphorus compound of formula (Y1 t=P(R1)(R2)X) (I), is new. X : Cl, Br, I, alkoxy or H; Y1 : O or S; t : 0 or 1; either R1, R2 : H, 1-16C alkyl, 2-16C alkenyl, 2-16 alkynyl, 1-16C alkoxy, 2-16C alkenoxy, 2-16C alkynoxy, 3-10C cycloalkyl, 3-10C cycloalkoxy, aryl, aryloxy, 6-10C-aryl-1-16C-alkyl, 6-10C-aryl-1-16C-alkoxy, 1-16C-(S-alkyl), 2-16C-(S-alkenyl), 2-16C-(S-alkynyl), 3-10C-(S-cycloalkyl), S-aryl, NH-1-16C alkyl, NHAryl, SR3, COR4, COOR5 or CONR6R7; or (R1+R2)+P : ring; and R3, R4, R5, R6, R7 : 1-16C alkyl, 2-16C alkenyl, 2-16C alkynyl, 3-10C cycloalkyl, aryl, aryl-1-16C alkyl, 1-16C-(S-alkyl), 2-16C-(S-alkenyl), 2-16C-(S-alkynyl) or 3-10C-(S-cycloalkyl). Independent claims are also included for: (1) preparing a polyurethane, comprising mixing isocyanates with polyols, a polycarbonate, optionally a blowing agent, a catalyst and other auxiliary agents and additives, and allowing to react to form a polyurethane; and (2) the polyurethane. |
