Abstract: 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.

Abstract: Degradable cross-linkers which are used to form polymer networks which degrade under aqueous conditions are described. These cross-linkers comprise a central polyacid, monomeric or oligomeric degradable regions and an optional water soluble regions. These monomers are preferably polymerized using free radical or condensation polymerization. Degradation occurs at the ester linkages after cross-linking polymer filaments, and results in soluble polymer filaments which may be cleared from the body. Preferred applications of these materials include, for example, controlled release of drugs and cosmetics, tissue engineering, wound healing, hazardous waste remediation, metal chelation, swellable devices for absorbing liquids and the prevention of surgical adhesions.

The invention also provides a non-halogen, flame-retardant polycarbonate resin composition having good flame retardancy, and its injection moldings having good impact strength and yellowing resistance even in high-temperature and high-humidity conditions and having good recyclability. The thermoplastic resin composition comprises 100 parts by weight of a resin mixture of (A) from 20 to 98% by weight of a polycarbonate resin and (B) from 2 to 80% by weight of a styrenic resin, from 0.1 to 20 parts by weight of (C) an epoxy-modified block copolymer and from 0.5 to 20 parts by weight of (D) a rubber-like elastomer component of a core/shell-type, grafted rubber-like elastomer. The flame-retardant polycarbonate resin composition comprises 100 parts by weight of a resin or resin mixture of (A) from 20 to 100% by weight of a polycarbonate resin and (B) from 0 to 80% by weight of a styrenic resin, from 1 to 30 parts by weight of (E) a flame retardant of an organic phosphorus compound, and from 0.1 to 10 parts by weight of (D) an epoxy group-containing compound.
