摘要：

Various physical and chemical properties of pitch fluoride such as chemical composition, molecular weight, specific gravity, dielectric constant, and water- and oil-repellency have been investigated as functions of the fluorination temperature between 30-degrees-C and 130-degrees-C. Bulk properties such as chemical composition, molecular weight, specific gravity and interlayer spacing vary according to the reaction temperature, while the surface properties are independent from it. Each property may be summarized as follows: chemical compositions were between CF1.00 and CF1.59; molecular weights were in the range 2070-4300; specific gravity was c. 2.00; refractive index was in the range 1.36-1.39; dielectric constant was c. 2.0. The contact angle of water was almost constant at c. 143-degrees, demonstrating the excellent water-repellency.
