Starch exanthates
Starch exanthates are derivatives of starch which belong to the starch esters .
Manufacturing
Starch exanthates are produced by reacting starch pretreated with alkaline with carbon disulfide (CS 2 ) in a polymer-like reaction . Since not all hydroxyl groups react in this reaction , mixtures are formed with different degrees of substitution . The degree of substitution of the individual starch components within a polymer can also vary.
application
They are used in the paper industry for paper strengthening and for the production of elastomers.
