Mkpụrụ osisi ether bụ polymer na-eme site na sellilose site na ngbanwe kemịkal. Celligul eather bụ ihe na-atọ ụtọ nke sellose. Mmepụta nke cellosuse eather dị iche na polymers sịntetik. Ihe kachasị mkpa bụ cellulose, polymer polymer. N'ihi ihe owuwu sellose eke, ihe cellulose n'onwe ya enweghị ikike imeghachi omume ndị ọrụ Ileration. Agbanyeghị, mgbe ọgwụgwọ nke onye na-ahụ maka ọzịza, a na-ejikọ hydrogen n'etiti ụdọ mmiri na agbụ nke hydroxyl na-emegharị alkali sellulose. Nweta celllose ether.
