12 Claims

1. A method for producing a copolymer composition, comprising:

a) submerging a water resistant polymer into a bath of a solvent, also referred to as solvent bath, and heating said solvent bath until the water-resistant polymer dissolves into the solvent bath resulting in a water-like solution;

b) forming a wax within the water-like solution by precipitating the wax from the water-like solution;

c) dispersing the wax in a liquid carrier resulting in a combination;

d) repolymerizing the wax into the water resistant polymer by introducing the combination into water-soluble polymer during an extrusion process resulting in a homogeneous copolymer mixture; and

e) programming the water solubility of the homogeneous copolymer mixture by changing a letdown ratio of the wax, said homogenous copolymer mixture defined as the copolymer composition.
