[0017] Example 1 (Production of 100,000 molecular weight products):

[0018] 1. After the speed of the stirring device 2 in the main body 1 of the polymerizer is set to 130 revolutions per minute, open the solvent feed valve on the solvent inlet 6-2, and drive 3m into the main body 1 of the polymerizer 3 Solvent, when the liquid level of the main body 1 of the polymerizer reaches 3m 3 When, close the solvent feed valve.

[0019] 2. Turn on the catalyst feeding device 3, and add the metered catalyst into the main body 1 of the polymerization vessel through the catalyst inlet 6-1; at the same time, turn on the shear 4.

[0020] 3. Open the cooling device 5 on the main body 1 of the polymerizer, make the cooling water circulate through the chilled water inlet 18 and chilled water outlet 13 on the cooling pipe 21, and turn on the ethylene oxide feed on the ethylene oxide inlet 6-3 The valve is used to feed ethylene oxide into the main body 1 of the polymerizer. During the reaction, the rea
