Polyoxymethylene (POM) bụ ụdị polymer linear na-enweghị yinye n'akụkụ, nke nwere nnukwu njupụta na nnukwu crystallinity, nke nwere ihe ndị mara mma.Ihe kacha pụta ìhè nke ihe a bụ modul ngbanwe ya dị elu, ike siri ike na isi ike.
POM bụ rọba kristal nwere ezigbo mmiri na steeti a wụrụ awụ.Ọ̀tụ̀tụ̀ shear na-emetụtakarị viscosity ya pụtara ìhè.Ọ bụ ihe na-enwe mmetụta shear,
Dịka usoro kemịkalụ dị iche iche nke ụdọ molekụla si dị, enwere ike kewaa polyoxymethylene n'ime homopolymerization na copolymerization.The homopolymer nwere nnukwu njupụta, crystallinity na n'ibu ike, ebe copolymer nwere ezigbo thermal nkwụsi ike, ịkpụzi usoro na acid na alkaline iguzogide.
