Webthe high-molecular-weight polyalkylene oxide has a viscosity in a 1% aqueous solution of 1500 to 16000 mPa·s, when the antioxidant is present, the antioxidant is present in an amount of less than 2000 mass ppm relative to the total mass of the high-molecular-weight polyalkylene oxide, and; the following formula (1): 0≤C 3 ×I×10 −8 <30 (1), Edward Frankland first reported the compound in 1848 from zinc and ethyl iodide, the first organozinc compound discovered. He improved the synthesis by using diethyl mercury as starting material. The contemporary synthesis consists of the reaction of a 1:1 mixture of ethyl iodide and ethyl bromide with a zinc-copper couple, a source of reactive zinc.
