The authors contemplated to prepare triol polyether by liquid phase polymerisation of propylene oxide using glycerine, trimethylolplopane or 1, 2, 6 hexanetriol as starting material and found that catalyst concentration and mole ratio of starting material to the oxide effected to the reaction velocity of polymerisation and the average molecular weight, colour and unsaturation of the polymer.
It was also studied to prepare polyether with tetraol or hexaol.
Further investigations were made on the conditions of purification of crude polyether such as neutralizing agent, filtering method and stripping method under reduced pressure.
