Ether cellulose na-abụghị ionic bụ ihe dị mkpa kemịkalụ nke ụlọ ọrụ ihe ụlọ na ụlọ ọrụ mkpuchi chọrọ. Ka ọ dị ugbu a, n'okpuru ndabere nke mmụba na-aga n'ihu na mkpokọta mmepụta nke ụlọ ọrụ ụlọ na mgbasawanye na-aga n'ihu nke ahịa mkpuchi, ahịa ahịa ya na-aga n'ihu na-eto eto.
Cellulose ether na-ezo aka na ngwakọta polymer nwere nhazi ether nke cellulose mere. Ọ bụ soluble na mmiri, itughari alkali ngwọta na organic mgbaze, na nwere thermos-plasticity.
