528354, 528357, 264165, 26417211, 26417217, 2641761, 428283, 428288, 428480, 422347
Abstract:

A nonwoven fabric comprised of a lactide polymer. The lactide polymer comprises a plurality of poly(lactide) polymer chains, residual lactide in concentration of less than about 2 percent and water in concentration of less than about 2000 parts-per-million. A process for manufacturing a nonwoven fabric with the lactide polymer composition is also disclosed.

US Patent:

7019170, Mar 28, 2006
Filed:

Oct 2, 1997
Appl. No.:

09/284160
Inventors:

Aharon Meir Eyal - Jerusalem, IL

International Classification:

C07C 59/08
C07C 51/42
US Classification:

562589, 562580, 562593, 562485
Abstract:

The invention provides a process for the recovery of lactic acid and products thereof from an aqueous solution containing free lactic acid and at least one lactate salt at a total concentration of at least 5%, the process comprising the steps of: extracting at least 70% of the free lactic acid from the aqueous solution by contacting the solution with a basic extractant, to form a lactic acid-containing extract and a lactic acid-depleted, lactate salt-containing aqueous solution; separating the lactic acid-containing extract from the depleted aqueous solution; and stripping the extracted lactic acid from the extract by methods known per se, to form a solution of lactic acid and a stripped extractant.

International Classification:

B32B 2708
B32B 2710
B32B 2736
B32B 3116
B32B 3130
US Classification:

428480
Abstract:

A compostable multilayer film includes a core layer having a first surface and a second surface, a first blocking reducing layer covering the first surface of the core layer, and a second blocking reducing layer covering the second surface of the core layer. The core layer comprises a lactic acid residue-containing polymer having a glass transition temperature (Tg) below 20. degree. C. At least one of the first and second blocking reducing layers comprise a semicrystalline aliphatic polyester. The core layer may be peroxide modified polylactide polymer which exhibits bridging between polylactide polymer chains.

US Patent:

6160173, Dec 12, 2000
Filed:

Oct 26, 1999
Appl. No.:

9/284108
Inventors:

Aharon Meir Eyal - Jerusalem, IL
Patrick R. Gruber - Blaine MN

Assignee:

Cargill Incorporated - Wayzata MN
International Classification:

C07C 51487
C07C 51493
US Classification:

562589
Abstract:

The invention provides a process for the recovery of purified lactic acid values from an aqueous feed solution containing lactic acid, lactic acid salt, or mixtures thereof, comprising: bringing the feed solution into contact with a substantially immiscible anion exchanger to form a substantially water-immiscible phase comprising an anion exchanger-lactic acid adduct; effecting a condensation reaction in the substantially water-immiscible phase between a carboxylic moiety of the lactic acid adduct and a moiety selected from a hydroxyl moiety and a primary or secondary amine moiety to respectively form a lactic acid ester or amine product; and separating the formed lactic acid product from the anion exchanger.
