    摘要: Organic inherently conductive polymers, such as those based on polyaniline, polypyrrole and polythiophene, are sequentially formed in-situ onto polymeric surfaces that are chemically functionalized to molecularly bond the conductive polymers to the substrates. The polymeric substrate is preferably a preshaped or preformed thermoplastic film, fabric, or tube, although other forms of thermoplastic and thermoset polymers can be used as the substrates for functionalization using, most preferably, phosphonylation-based processes followed by exposure to an oxidatively polymerizable compound capable of forming an electrically conductive polymer. It has been found that the degree of electrical conductivity may be modulated by bonding further electrically conductive layers to the article. That is, each underlying conductive layer is functionalized prior to bonding of a subsequent conductive layer thereto until the degree of conductivity is achieved. In an alternative embodiment, metals such as gold or platinum may be bonded to one of the functionalized surfaces.

    摘要: A method for modifying a protein or polypeptide is disclosed which includes the steps of dispersing a protein or polypeptide in an essentially non-aqueous medium and peracylating the protein or polypeptide with a cyclic anhydride having a carbon chain substituent selected from the group consisting of alkyl and alkenyl groups. Most preferably, the cyclic anhydride is succinic anhydride, although glutaric anhydride may also be employed. Preferably, the step of peracylating the protein or polypeptide is performed in the presence of an acid catalyst, most preferably .rho.-toluene sulfonic acid. The resultant modified protein or polypeptide may be employed in numerous applications including drug delivery, absorbable sutures, and thermoplastic films and molded articles.

    摘要: An inorganic glass having an aliphatic polymer covalently bonded to the surface thereof is disclosed for providing improved adhesion to a matrix polymer when the glass is employed as a composite filler, as well as for the formation of a composite absent a separate matrix polymer. The polymer is grafted onto the glass by a method which includes the steps of pretreating the surface of the glass with an activator which an activating moiety to the surface, functionalizing the pretreated surface by bonding functional moieties thereto, and polymerizing a cycloaliphatic monomer onto the functionalized surface in the presence of a ring opening polymerization catalyst. Also disclosed are novel inorganic glasses which contain both silicate and phosphate linkages.
