Abstract
High molecular weight ethylene (meth)acrylic acid (EAA) dispersions and methods for producing the same are provided. An exemplary method for producing a high molecular weight ethylene (meth)acrylic acid (EAA) dispersion includes mixing an ethylene/(meth)acrylic acid (EAA) copolymer, having a mass flow index (MFI) of no greater than about 300 g/10 min at 190° C. and 2.16 kg, and a base at a temperature of at least about 100° C. to form a molten phase in which the EAA copolymer is relaxed by the base. The exemplary method further includes mixing water with the molten phase at least until the molten phase disperses into the water to form the high molecular weight EAA dispersion.
