Electrostatic separator polyethylene

The EMA anhydride resins may be treated with iV,7V-dialkylaminoal-cohols to produce polyampholytes, ammonia, and primary or secondary amines to produce amides and a host of other mono and polyfunctional active hydrogen compounds to produce a wide variety of derivatives. The primary amine derivatives, i.e., amide-ammonium salts, may be transformed with heat to imide copolymers.Surface tension studies have been explored on EMA resins and octadecylamine derivatives of the copolymer.The effect of steric hindrance on accessibility, inhomogeneous consideration, electrostatic effects, etc., on the reaction of typical aliphatic amines and polymeric amines (polyethylene imine) with propylene-MA copolymer have been recently examined in great detail.The complexity of the reaction did not allow complete separation of the many variables.
