    摘要: A composition for forming a resist underlayer film that enables the formation of a desired resist pattern; and a method for producing a resist pattern and a method for producing a semiconductor device, each of which uses the composition for forming a resist underlayer film. (In formula (1), A1, A2, A3, A4, A5, and A6 each independently represent a hydrogen atom, methyl group, or ethyl group; Q1 represents a divalent organic group; R1 represents a tetravalent organic group; and R2 represents an alkenyl group or alkynyl group having 2-10 carbon atoms.) The film-forming composition contains a solvent and a polymer that has a unit structure given by formula (1).

    摘要: An anti-tumor nano adjuvant is obtained by loading a drug on the vesicle formed by a reversibly cross-linked biodegradable polymer with an asymmetric membrane structure; the drug is an oligonucleotide activating an immune response; the vesicle formed by the degradable polymer is obtained by the self-assembly of a polymer followed by cross-linking; the molecular chain of the polymer includes a hydrophilic chain segment, a hydrophobic chain segment and positively charged molecules, successively connected; the hydrophobic chain segment is a polycarbonate chain segment and/or a polyester chain segment, which is compounded and loaded with a drug by electrostatic interaction; and the membrane is a polycarbonate chain segment and/or a polyester chain segment, which is reversibly cross-linked, biodegradable and has good biocompatibility, the dithiolane in the side chain thereof is similar to thioctic acid, a natural antioxidant in human body, and the shell thereof is based on PEG and targets cancer cells.
