Abstract

A copolymer composition including a method having a first step involving heating and submerging of water-resistant polymer into a solvent bath until the water-resistant polymer dissolves into the solvent bath resulting in a water-like solution. A second step includes precipitating the water-like solution forming a wax within the water-like solution. A third step involving filtering and distilling of the water-solution separating the wax from the solvent bath. A fourth step involving dispersing of the wax in a liquid carrier resulting in a combination. A fifth step involving polymerizing of the wax into the water-resistant polymer by introducing the combination into water-soluble polymer during an extrusion process resulting in a homogeneous mixture. A sixth step involving programming the water solubility of the homogeneous mixture. Resulting in the copolymer composition having programmable water solubility, shelf-life stability and quality in the presence of moisture or liquids for a predetermined length of time.

Claims (17)

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.

2. The method of claim 1 , further including selecting a compatible solvent, depending on the water-resistant polymer, so that the solvent dissolves said water-resistant polymer into a wax state at a verge of polymerization.

3. The method of claim 2 wherein said solvent bath is maintained at a predetermined temperature range.

4. The method of claim 3 , wherein a lower temperature limit from said predetermined temperature range is calculated as O_min=(T/E_min)×100; wherein said O_min is a minimum optimal temperature for dissolution; wherein said T is a boiling point of said solvent; and E_min is a constant value of 63.48.

5. The method of claim 3 , wherein an upper temperature limit from said predetermined temperature range is calculated as O_max=(T/E_max)×100; wherein said O_max is a maximum optimal temperature for dissolution; wherein said T is a boiling point of said solvent; and E_min is a constant value of 38.59.

6. The method of claim 1 wherein said solvent is a liquid that causes depolymerization of said water resistant polymer.

7. The method of claim 1 wherein said resistant polymer is submerged within said solvent bath for a length of time between 15 and 30 minutes.

8. The method of claim 1 wherein said water-like solution, after precipitating, forms said wax, wherein said wax is a thin powder.

9. The method of claim 8 wherein the thin powder forms a viscous cloudy liquid when molten.

10. The method of claim 1 wherein said liquid carrier is synthetic or natural, said liquid carrier further having a high smoke point.

11. The method of claim 1 wherein water solubility of the homogeneous copolymer mixture is proportional to an amount of the wax used.

12. The method of claim 1 , wherein the homogeneous copolymer mixture has a programmable shelf life and a short environmental lifespan.
