Patent GB-357488-A (GB)
IPC: C08F36/04
Filed: 1930-03-18
Abstract: The polymerization of diolefines by means of alkali metals is controlled by adding a limited quantity of available water preferably as water of crystallization, the solution of the water checking the polymerization, so that by choosing a compound having a suitable vapour pressure of water, a desired grade of product may be obtained. The crystalline substances mentioned are calcium chloride, sodium carbonate and sulphate, alum, and magnesium sulphate.  The water added must not be so much as to combine with all the alkali metal. In an example, butadiene is polymerized at 30 DEG  C. for 4 days in a rotary autoclave with sodium and hydrated sodium sulphate, the sodium and sodium sulphate being washed out with water on the wash rollers at the end of the process.  Other examples describe the polymerization of butadiene with sodium in presence of hydrated calcium chloride and sodium carbonate respectively.
