The surface tension and liquid kinematic viscosity of two binary refrigerant mixtures 1,1,1,2- tetrafluoroethane (R134a) (1) + 2,3,3,3-tetrafluoroprop-1-ene (R1234yf) (2) and R134a (1) + trans- 1,3,3,3-tetrafluoroprop-1-ene (R1234ze(E)) (2) were measured in the temperature range from 293 K up to the liquid-vapor critical point with the surface light scattering (SLS) method. The experimental data were correlated as a function of temperature and mole fraction of the pure components. For surface tension, the average absolute deviations are 0.019 mN m-1 for R134a + R1234yf and R134a + R1234ze(E). For liquid viscosity, the average absolute deviations are 0.96% and 1.16% for R134a + R1234yf and R134a + R1234ze(E), respectively.
