    摘要: An outer layer having an entanglement comprising an intermingling of cloaked hydrophilic guest and a hydrophobic polymer host, wherein molecules of the guest have been crosslinked with each other. Under certain circumstances, using complexes of the guest may be desirable or even necessary. The intermingling of the guest and host includes a physical tangling, whether it also comprises crosslinking by primary bonding (e.g., chemical/covalent bonding) there-between. Also a method of producing an outer layer having such an entanglement, including the steps of: temporarily cloaking at least a portion of the hydrophilic groups of the guest; intermingling at least a portion of the cloaked groups with a porous polymeric structure by diffusing the guest with cloaked groups into at least a portion of the structure's pores; within the pores, crosslinking at least a portion of the molecules of the guest with the guest; and removing the cloaking. Cloaking may be performed by silylation or acylation. Intermingling may be performed by producing a mixture of guest and host (whether in solution, powdered, granular, etc., form); next, a crosslinking of the guest with itself is performed; then, the mixture is molded into the outer layer.

    摘要: An outer layer material having an entanglement comprising an intermingling of cloaked hydrophilic guest and a hydrophobic polymer host, wherein molecules of the guest have been crosslinked with each other. Under certain circumstances, using complexes of the guest may be desirable or even necessary. Prior to intermingling with the guest, a host blend may be produced to include a physical blend of a hydrophobic polymer host and a maleated hydrophobic co-host (preferably, an anhydride functionalized hydrophobic polymer, whereby the polymer so functionalized, is the same as that selected for the host). The intermingling of the guest and host, or host-co-host blend, includes a physical tangling, whether it also comprises crosslinking by primary bonding (e.g., chemical/covalent bonding) there-between. Also a method of producing an outer layer material having such an entanglement, including the steps of: temporarily cloaking at least a portion of the hydrophilic groups of the guest; intermingling at least a portion of the cloaked groups with a porous polymeric structure by diffusing the guest with cloaked groups into at least a portion of the structure's pores; within the pores, crosslinking at least a portion of the molecules of the guest with the guest; and removing the cloaking. Cloaking may be performed by silylation or acylation. Intermingling may be performed by producing a mixture of guest and host, or host blend, (whether in solution, powdered, granular, etc., form); next, a crosslinking of the guest with itself is performed; then, the mixture is molded into the outer layer with or without additional crosslinking of the host to the host.

    摘要: A series of novel, melt- or mold-processable HA esters with varying aliphatic chain lengths are synthesized from silyl HA-quaternary (quat.) ammonium salt complex (preferably silyl HA-CTA, a silylated HA complex with cetyltrimethyl ammonium salt). Introduction of aliphatic acyl groups, preferably acid chlorides, to disrupt the strong HA intermolecular bonding, is done via acylation. Acylation takes place at the oxygen of the trimethylsilyloxy group —O—Si(CH3)3 in the silyl HA-CTA by removal of trimethylsilyl groups therefrom. Optionally, crosslinking may be performed during the shaping/molding of the HA esters into a structure/device, or thereafter, if at all. Native HA can then be regenerated/recovered by saponification hydrolysis, removing acyl groups, —CH3(CH2)10CO, and the cetyltrimethyl ammonium salt groups, -CTA, from HA ester. The structure/device of a preselected shape (e.g., porous or solid, bulk structure or fibers) may become a component of an assembly, a product that is further processed, integrated into another component (e.g., laminated, adhered, assembled, further shaped, chemically-intermixed/intermingled), and so on.

    摘要: This invention belongs to the field of biochemical engineering and relates to a method of cyclic utilization of water during separation of succinic acid made by fermentation. This invention uses water from separation process for aerobic growth of E. coli AFP111 and production of succinic acid by anaerobic fermentation, obtaining final succinic acid concentration of 55 g/L and yield of 91.6%. Compared with results of fermentation using culture medium prepared from tap water, succinic acid concentration and productivity increased by 8.5% and 8.46%, respectively. An outstanding advantage of this invention is recovery and utilization of evaporated water during separation of succinic acid, realizing cyclic use of water during industrial production of succinic acid, which is an environment-friendly process. Also, as evaporated water generated during separation of succinic acid contains small amount of organic acids such as acetic acid and formic acid, if this water is used for aerobic growth of thalli, the small amount of organic acids contained therein can be used as gluconeogenesis carbon source, improving activity of some key enzymes in cell and favoring succinic acid production by anaerobic fermentation of thalli.
