Abstract:
1. A method of making a heterogeneous polymer blend, comprising: a. adding to a non-neutral solution a first amount of a polymerization initiator and one or more anionic or cationic monomers, wherein each monomer has the same charge; b. adding a second amount of the polymerization initiator and one or more non-ionic monomers to the solution; c. adding a third amount of the polymerization initiator and one or more ionic monomers that are oppositely charged from the monomers of (a); d. adding stepwise, a fourth amount of the polymerization initiator to react any residual monomer and resulting in the heterogeneous polymer blend; and e. neutralizing, if necessary, the resulting heterogeneous polymer blend.
