ABSTRACT:
The invention relates to an improved cationic starch. This starch is composed of a major portion of starch which has been modified with a water-soluble cationic polymer comprising at least 10 mole percent of the dimethyl sulfate or the methyl chloride quaternary ammonium salt of 1-acryloyl-4-methyl piperazine. The invention also contemplates using such cationic starches to modify papers and the improved papers so treated.
