Quaternized Starch Fiber Strengthening Agent

Linear form for rigidity

Amylose-based strengthening agent forms a thin, rigid adlayer on fibers, with enhancement rising with degree of substitution, unlike amylopectin.

Advantages

Paper strength enhancement of quaternized amylose correlates positively with degree of substitution

Paper strength enhancement of quaternized amylopectin correlates inversely with degree of substitution

Amylose adlayer is thin and rigid, while amylopectin adlayer is thick and soft
