Eter cellulose

Eter-ka cellulose waa koox ka mid ah derivatives cellulose la bedelay, halkaas oo kooxaha hydroxyl (-OH) ee molecules cellulose lagu beddelo kooxaha ether (-OR). Wax ka beddelladani waxay kor u qaadaan sifooyinka cellulose, taasoo ka dhigaysa mid faa'iido badan u leh warshadaha kala duwan.

Cellulose Ether waxay caddeeyeen inay yihiin polymers-ku-saleysan dabiici ah oo aad waxtar u leh, helitaanka codsiga meelaha ay ka mid yihiin cuntada, alaabta daryeelka shakhsi ahaaneed, kiimikooyinka goobta saliidda, dhismaha, waraaqaha, dhejiska, iyo dunta;

Waxay qiimo gaar ah ku leeyihiin codsiyada dawooyinka iyadoo ay ugu wacan tahay sifooyin ay ka mid yihiin heerkulka kala-guurka dhalada sare, xasilloonida kiimikaad sare iyo kiimikaad sare, milanka, crystallinity xaddidan, awoodda isku xidhka hydrogen, iyo sunta hoose;
