| abstract | Oxymethylene copolymers contain oxymethylene groups to the extent of at least 80% together with oxyalkylene groups, some of the latter being derived from molecules of an oxacyclic compound having a substituent alkylol group. Specified oxacyclic compounds are the 3 - alkyl - 3 - (hydroxy alkyl) oxetanes especially 3-ethyl-3-(hydroxymethyl) oxetane, hydroxypropyl glycidyl ether, pentaerythritolmonoformal, 3,3-dihydroxy ethyl oxetane, 3-ethyl-3-(hydroxy ethyl)-1,5-dioxane and 3- ethyl - 3 - (hydroxy methyl) tetramethylene oxide. A third comonomer containing oxyalkylene units, e.g. oxyethylene, may also be present. The polymers may be made by copolymerizing trioxane and its comonomers with boron fluoride or a complex thereof or other Lewis acids under anhydrous conditions in a solvent medium. A chain transfer agent, e.g. methylal, may be present. |
