Claim:
1. A poly(2-oxazoline-co-ethyleneimine)-epichlorohydrin copolymer, comprising: (1) Hydrophobic N-acyl-iminoethylene monomeric units in an amount (designated as M1) of from about 2% to about 95% by mole, wherein the N-acyl-iminoethylene monomer units have a formula of where R1 is a monovalent radical R1b which is C (2) azetidinium monomeric units in an amount (designated as M2) of from about 0.5% to about 95% by mole, wherein the azetidinium monomeric units have a formula of (3) ethyleneimine monomeric units in an amount (designated as M3) of from 0 to about 60% by mole, wherein the ethyleneimine monomeric units have a formula of *—NH—CH2—CH2—* and (4) crosslink units in an amount (designated as M4) of from 0 to about 5% by mole, wherein the crosslink units have a formula of provided that (M1+M2+M3+M4) is about 100%.
