ABSTRACT:
Poly(vinylamine) homopolymers and copolymers are hydrophobically modified by reaction of amine units present in the polymer with a saturated aliphatic or aromatic glycidyl ether compound. The resulting polymers are useful as flocculants in separating water from suspended solids and are especially effective in improving fines retention in papermaking. Poly(vinylamine hydrochloride) modified in this manner with butyl glycidyl ether is shown to be very efficient in retaining the paper product fines present in recycle paper pulps.
