The polymerization of trioxan, initiated by boron trifluoride n-butyl etherate, has been studied in cyclohexane solution at 50 Β°, 65 Β° and 70 Β°. Correlations have been obtained between the yields and inherent viscosities of the polymer and the main reaction variables. Increasing the concentration of
In the cationic polymerization of trioxane initiated by BF, etheratc in cyclohexane solution, the rate of polymerization may be practically zero after a long period at 56 Β°. If the reaction mixture is then cooled at a controlled rate, it is possible to obtain further increments both in yield and in
Cationic polymerizations of trioxane in 1,2-ethylene dichloride and benzene were heterogeneous and reversible. Phase separation accompanying with crystallization occurred during the polymerization. Three morphological changes were found in the course of the polymerization as were investigated by dil
## Abstract The possibility of electroinitiating the polymerization of melted trioxane dispersed in __n__hexane and __n__βheptane has been investigated. It was found that the addition under stirring of an electrolyte to these dispersions added a satisfactory electrolytic conductivity: this fact all
