    摘要: Aliphatic polyesters of 3,4'-biphenyldicarboxylic acid and optionally 4,4'-biphenyldicarboxylic acid are prepared by contacting at least one aliphatic diol having from 2 to 12 carbon atoms with a lower alkyl diester or phenolic diester of 3,4'-biphenyldicarboxylic acid and, optionally, a lower alkyl diester or phenolic diester of 4,4'-biphenyldicarboxylic acid, in the presence of a catalyst at about 180.degree. to about 300.degree. C. These polyesters are suitable for use in making fibers, films, three dimensional molded articles, barrier containers and coatings.

    摘要: Methods for producing degradable particulates and slurries thereof, and methods related to the use of such degradable particulates and slurries in subterranean applications. Among the many methods provided are methods comprising: providing a degradable material mixture that comprises a degradable material and a first solvent; providing a fluid that comprises a second solvent and a surfactant, wherein the first and second solvents are immiscible in each other; combining the degradable material mixture and the fluid with sufficient shear to form an emulsion that comprises a discontinuous phase and a continuous phase, the discontinuous phase comprising the degradable material mixture and the continuous phase comprising the second solvent; removing at least a portion of the first solvent from the discontinuous phase; and forming a plurality of degradable particulates. Other methods are also provided.

    摘要: Methods of creating degradable particulates in a subterranean environment. The methods provide a degradable material supercritical fluid mixture that comprises degradable material into a wellbore penetrating a subterranean formation and provide an orifice between the wellbore and the subterranean formation wherein the pressure in the subterranean formation is less than the pressure in the wellbore. The degradable material supercritical fluid is then fed through the orifice into the subterranean formation such that the degradable material supercritical fluid mixture expands through an orifice into the lower subterranean formation and particulates are formed.

    摘要: A method of making a biodegradable polymer composition including the steps of providing a first component being either one of a thermoplastic poly(hydroxy ester ether) or a synthetic, hydroxy-functional polymer and providing a second component being a natural polymer. The method includes the steps of mixing the first component and second component together to form a mixture, compounding the mixture, and pelletizing the compounded mixture to form pellets of a biodegradable polymer composition.
