Surface sizes for paper were prepared by enzyme conversion of cationic aminoethyl flours and starches. Aminoethylation of corn and wheat flour and starch was accomplished with ethylenimine. In laboratory surface sizing studies, the sizes were comparable to commercial cationic starch sizes in improving paper strength and surface properties. All of the cationic products were highly retained when the paper was recycled.
