Ethyl cellulose(EC) and methyl cellulose (MC) are cellulose derivatives with a relatively similar chemical structure. EC is a partially ethylated cellulosic ether prepared by reacting alkali cellulose with ethyl chloride. Different types of EC, usually distinguished by their viscosity, molecular weight...
