ABSTRACT:
The molecular weight of cationic polymers, such as diallyldialkyl ammonium chloride, can be increased by controlled addition of a water-soluble radical initiator at an elevated reaction temperature with agitation to prepare high molecular weight, crosslinked, water-soluble cationic polymers.
