Self-degrading fibers and associated methods of use and manufacture
 
Mang and Todd of Halliburton Energy Services, Oklahoma, developed self-degradable fibers consisting of hollow fibers with an outer shell, and a core liquid.  One example is poly(lactic acid) fibers with internal water.  About 0.25 grams of water is needed for 1 gram of poly(lactic acid).  Nonlimiting examples of degradable polymers that may be used in the self-degrading fibers of the present invention include, but are not limited to, homopolymers, random, block, graft, and star- and hyper-branched aliphatic polyesters.  Specific examples of suitable polymers include aliphatic polyesters; poly(lactides); poly(glycolides); poly(.epsilon.-caprolactones); poly(hydroxybutyrates); polyanhydrides; aliphatic polycarbonates; poly(orthoesters); poly(amides); poly(urethanes); poly(hydroxy ester ethers); and poly(phosphazenes).  (RDC 6/7/2012)
