Definitions
- Preferred phenols have the formula OH Y I H wherein X is halogen or nitro and Y is hydrogen, halogen or nitro.
- the polymers are made by polymerizing at least one mole of a cyclic oligomer of formaldehyde, e.g. trioxane with the corresponding phenol with a catalyst suitable for polymerizing trioxane.
