Polyoxymethylene
POM (as it's also called) can be made from the cyclic trimer of formaldehyde trioxane.
POM is a polyether like PEO and polyTHF. It is also called polyacetal and polyformaldehyde,
indicating synthesis from a different monomer, formaldehyde. Both syntheses
require end-capping with ethylene glycol or acetic anhydride to stop depolymerization.
POM is highly crystalline, tough and self-lubricating which makes it ideal for use in many applications such as
small bearings and drawer slides, and automotive applications where fuel resistance is important.
