Water dispersible polyamides having carboxylic acid groups are disclosed. These are made by reacting polycarboxyl is acids or anhydrides thereof with amine containing monomer or an amide terminated polyamide under reaction conditions such that a few of the carboxylic acid groups are residual and can promote dispersion in water. These polyamides after dispersion can be chain extended to higher molecular weight polymers or can be terminally functionalized with reactive groups such as isocyanate, epoxy, vinyl, acetoacetonate, or silanol groups. Composites and hybrids of these polyamides with vinyl polymers are also disclosed and claimed.

Poly(amine-co-ester) polymers, methods of forming active agent-load polyplexes and particles therefrom, and methods of using them for delivery of nucleic acid agents with optimal uptake have been developed. Examples demonstrate critical molecular weights in combination with exposed carboxylic and/or hydroxyl groups, and methods of making. Typically, the compositions are less toxic, more efficient at drug delivery, or a combination thereof compared to a control other transfection reagents. In some embodiments, the compositions are suitable for in vivo delivery, and can be administered systemically to a subject to treat a disease or condition. For poly(amine-co-ester) polymers with specific amine or hydroxyl group containing end-groups in admixture with PEGylated poly(amine-co-ester) polymers, in vivo delivery to the lung by inhalation has been shown.

The present invention relates to a composite semipermeable membrane including: a support membrane including a base and a porous support layer; and a separation functional layer disposed on the porous support layer and including a crosslinked aromatic polyamide, in which the separation functional layer contains sulfo groups in an amount of 7.0×10.sup.−5 to 5.0×10.sup.−2 g/m.sup.2 and includes a structure represented by the formula 1.

The present disclosure relates to the field of polymer chemistry and more particularly to poly(sarcosine) polymers and uses thereof. The disclosure is also directed to compositions comprising a protein and a poly(sarcosine) polymer and uses thereof.

The invention relates to new cationic polymers conjugated with D-fructose, as a result of which they can selectively interact with specific structure elements on cell surfaces. The problem was that of creating novel, biocompatible, easy-to-produce, D-fructose-conjugated cationic polymers that have a higher selectivity with respect to certain cell types. To solve this problem, the invention proposes cationic polymers with covalently bonded D-fructose of general formula (I) with the following components: a) cationic polymer: macromolecular compounds of n repeat units with one or more positive charges; b) linker: a unit that links the cationic polymer with D-fructose or derivatives of D-fructose by means of any alkyl or aryl group, any alkenyl or alkinyl group, an ether, thioether or amine, an ester, amide or other carboxylic acid derivative, a heterocycle (e.g. triazole or m maleimide), a disulphide, an imine or an imide; c) D-fructose: one or more D-fructoses or D-fructose derivatives in an open-chain, furanoid or pyranoid structure, not glycosidically linked via one of the five possible carbon atoms (1, 3, 4, 5, 6).
