摘要： A process for the continuous production of polylactide polymers from lactic acid which incorporates removal of water or a solvent carrier to concentrate the lactic acid feed followed by polymerization to a low-molecular-weight prepolymer. This prepolymer is fed to a reactor in which a catalyst is added to facilitate generation of lactide, the depolymerization product of polylactic acid. The lactide generated is continuously fed to a distillation system as a liquid or vapor wherein water and other impurities are removed. The resultant purified liquid lactide is fed directly to a polymerization process.

摘要： A process for the continuous conversion of crude lactic acid to a substantially purified lactide or polylactide including the steps of polymerizing the lactic acid to form a prepolymer with subsequent depolymerization to form a crude lactide in the presence of a catalyst. The crude lactide is purified in an improved distillation system in which at least three fractions are formed with the substantially purified lactide removed as an intermediate boiling sidedraw stream. The substantially purified lactide may then be polymerized.

摘要： A barrier sheet having a first side and a second side, a top edge, a bottom edge, and a laterally located midpoint, wherein the sheet is folded along its length to form a folded sheet defined by at least one fold with an adhesive strip positioned at a predetermined distance from the top and bottom edges, and preferably approximately at the sheet midpoint. When making a roll of barrier material, a barrier sheet material is provided and folded at least once laterally. The sheet then incorporates an adhesive strip applied to one side of the sheet at a predetermined distance from the top and bottom ends, preferably approximately at the midpoint. The adhesive strip is oriented lengthwise such that when the sheet is unrolled from the roll and unfolded, the strip will approximately bisect the sheet lengthwise. The sheet is then folded in a predetermined fashion, and rolled onto a roll. Further, when applying the barrier material to a structure, a predetermined length of folded sheet is extended and cut from the roll. The free, but still folded sheet is affixed to the structure by removing a backing material from the adhesive strip and pressing the product against the structure. The sheet can then be unfolded to form a 2-ply barrier.
