摘要： A copolymer composition including a method having a first step involving submerging of LDPE into a heptane bath and heating the heptane bath until the LDPE dissolves into the heptane bath resulting in a water-like solution. A second step including precipitating of the water-like solution forming a PE wax within the water-like solution. A third step involving filtering and distilling of the water-like solution separating the PE wax from the heptane bath. A fourth step involving dispersing of the PE wax in a liquid carrier resulting in a combination. A fifth step involving polymerizing of the PE wax into LDPE by introducing the combination into PVA during an extrusion process resulting in a homogeneous mixture. A sixth step, 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 for a predetermined length of time.
