Abstract
A compatibilizer for polymer blends is presented. The compatibilizer comprises a sulfonated polystyrene and may be used to prepare miscible blends of the sulfonated polystyrene with two or more polymers having polar groups, e.g., polyamides, polyethers, polyesters, polysulfones and polyamines. The sulfonated polystyrene compatibilizer may be used in conjunction with a counterion.
