FIELD: chemistry.
SUBSTANCE: polymer mixture consists of thermoplastic polyurethane (TPP) and a modified impact resistant methylmethacrylate polymer. Said impact-resistant methylmethacrylate polymer is modified with an impact resistant modifier with a "nucleus/shell/shell" structure. The first shell contains 80-98 wt % repeating (meth)acrylate monomers and 2-20 wt % styrene monomers of a defined formula (1). The second shell contains 50-100 wt % repeating alkylmethacrylate units, having 1-20 carbon atoms, 0-40 wt % repeating alkylacrylate units, 0-10 wt % styrene monomers of formula (1). The nucleus contains 50-99 wt % alkylmethacrylate repeating units having 1-20 carbon atoms, 0-40 wt % alkylacrylate repeating units having 1-20 carbon atoms, 0.1-2.0 wt % cross-linking repeating units and 0-8.0 wt % styrene monomers of formula (1).
EFFECT: polymer mixture is used to obtain moulded articles with high light transmission and high impact resistance at above-zero and subzero temperatures.
