ABSTRACT:
Methylated, ethylated or carboxymethylated starch products which have, per anhydroglucose unit within the starch molecule, an average of from about 0.03 to about 1.0 methyl, ethyl or carboxymethyl substituents covalently bonded thereto and which contain a combined total of less than 1 weight percent, on a dry starch solids weight basis, of polyvalent inorganic anions, monovalent inorganic anions and methylsulfate and ethylsulfate anions are particularly well suited for use as protective colloids in emulsion polymerization or copolymerization processes.
