The present invention provides a conductive polymer composition which contains (A) a polyaniline-based conductive polymer having a repeating unit represented by the general formula (1), (B) a polyanion, and (C) a betaine compound, ##STR00001##
wherein R.sup.A1 to R.sup.A4 independently represent a hydrogen atom, a halogen atom, or a linear, branched, or cyclic monovalent hydrocarbon group having 1 to 20 carbon atoms and optionally containing a heteroatom; and R.sup.A1 and R.sup.A2, or R.sup.A3 and R.sup.A4 may be bonded to each other to form a ring. There can be provided a conductive polymer composition that has excellent antistatic performance and applicability, does not adversely affect a resist, and can be suitably used in lithography using electron beam or the like.

Provided herein are (phenylene)dialkanamines, and methods of producing such (phenylene)dialkanamines from various furanyl and benzyl compounds. Such furanyl compounds may include, for example, bis(nitroalkyl)furans, bis(aminoalkyl)furans, and nitroalkyl(furan)acetonitriles. Such compounds may include, for example, bis(nitroalkyl)benzenes. Provided herein are also alkyldiamines, and methods for producing such alkyldiamines from furanyl compounds.

The present invention relates to dispersants based on polyamines or polyimines containing side chains based on two or more poly(oxy-C.sub.1-6-alkylenecarbonyl) compounds (A) and side chains based on alkyl acid (B).

Provided is a gene delivery including a polymer network formed by binding phenylboronic acid, sugar, and a low-molecular weight branched polymer. The gene delivery may be stably maintained in vivo and efficiently deliver a gene specifically to cancer cells, such that the gene delivery system may be usefully used as a gene delivery system for chemotherapy.

Provided is an ethyleneimine polymer which exhibits excellent close adhesion properties and adhesive properties and is unlikely to form a gel-like film, and a method for producing the same. An ethyleneimine polymer, wherein a number average molecular weight (Mn) of the ethyleneimine polymer measured by gel permeation chromatography in terms of pullulan is 13,000 or more, a degree of dispersion of the ethyleneimine polymer is greater than 3.0 and 5.0 or less, and a water content in the ethyleneimine polymer is from 3 to 35% by weight.

The present invention relates to polydixylitol polymer based gene transporter (PdXYP) and a preparation method thereof. Further, the present invention relates to a nucleic acid delivery complex where the nucleic acids for treatment are conjugated to the gene transporter and a pharmaceutical composition for gene therapy including the complex as an active ingredient. In addition, the present invention relates to the gene transporter, gene delivery complex, and gene therapy using the gene transporter and gene delivery complex. It was confirmed that the PdXYP of the present invention has a considerably higher nucleic acid delivery rate than existing gene transporters, has almost no cytotoxicity in the conjugate when conjugated with DNA, also has very high in vivo transfection efficiency, and above all, especially has considerably high transfection efficiency for brain tissues, which has involved difficulty in gene therapy due to the blood brain barrier for a while. Accordingly, the gene transporter of the present invention can not only be used as experimental gene transporters, but can also be broadly used for various tissues in the body based on the nucleic acids for treatment to be conjugated in the field of gene therapy regarding various diseases.

Hydrophobically modified Si-containing polyamines are useful for treating scale in industrial process streams. Preferred hydrophobically modified Si-containing polyamines are particularly useful for treating aluminosilicate scale in difficult-to-treat industrial process streams, such as in the Bayer alumina process streams, nuclear waste streams and kraft paper mill effluent streams.
