  • Publication number: 20140274820
    Abstract: The present disclosure is directed degradable polymers. The polymers are solid when maintained under substantially dry conditions at a temperature of up to about 90 degrees C. When contacted with water at a temperature of up to about 90 degrees C., however, the polymers initially remain solid for a period of up to about 6 to about 24 hours, then depolymerize to provide a liquid having a viscosity of from about 1 to about 200,000 centipoise after a period of time from about 8 hours to about 3 days and then further depolymerizes to water-soluble components after a period of time at least about 3 days. Also disclosed are sand screen coatings made with the polymers and hydraulic and acid fracturing methods using the polymers.

  • Patent number: 5850032
    Abstract: The present invention relates to making precocious neomorphic embryoids (PNE) and their use for producing biological products. Specifically, the invention provides a method for increasing taxol production from embryogenic Taxus cultures by making precocious neomorphic embryoids.The invention further provides methods of inducing somatic embryogenesis in tissue cultures derived from varieties of Taxus. In addition, the present invention provides methods of obtaining taxol, or precursors thereof, using in vitro propagated somatic embryo tissues.
