POM COMPOUND

Acetal polymers are properly called polyoxymethylene (POM). This resin is linear unbranched molecular chains derived frorn the monomer formaldehyde (anhydrous). The acetal homopolymer is manufactured by polymerization of formal dehyde, where as its copolymers is made trioxane, the cyclic trimer of formaldehyde

Properties

This is typically produced from an alkaline precipitated low molecular weight polyformaldehyde which has been carefully washed with distilled water and dried for several hours under vacuum at about 80 c. The dried polymer is then pyrolysed by heating at 150-160°C, and the resultant formal dehyde passed through a number of cold traps (typically four) at - 15°C
