    摘要： A mold-releasing and lubricating silicone oil has the following general formula: R¹ a R² b SiO (4-a-b)/2
    wherein R¹ represents X-R³-; R³ is C₁₋₈ and X is NH₂ or NHR⁴NH₂,R⁴ being C₁₋₈ alkylene; R² is a monovalent C₁₋₆ hydrocarbon group; and "a" and "b" satisfy the relations 0.001 ≦ a ≦ 0.01 and 1.95 ≦ a + b ≦ 2.20. The oil has a viscosity of 10 to 100,000 cs at 25°C, an amine equivalent of 10,000 to 100,000, excellent thermal resistance, and high affinity for the surfaces of metal or metal oxide molds.
