The invention relates to the technical field of in vitro detection, in particular to a kit for measuring glucose content and its application. The kit includes an anti-chylopathic interference reagent selected from the group consisting of poly(ethylene oxide) fatty alcohol nonionic surfactants, poly(ethylene oxide-propylene oxide) fatty alcohol nonionic surfactants. One or more of the non-ionic surfactants of polyethylene glycol alkyl ethers, mixed fatty acid glycerides non-ionic surfactants. The invention is based on the basic components of the glucose determination kit, and adds 0.01% to 10% of one or several specific surfactants in the detection reagent, so as to eliminate the interference of chyle in the lipid blood sample to the glucose determination, and improve the lipid blood level. The accuracy of glucose detection in the sample; the reagent composition is simple, easy to produce and prepare; the cost is low, and it is easy to commercialize.

The invention discloses a preparation method of a second monomer for an acrylonitrile-based copolymer solid-solid phase change material, a method for preparing the acrylonitrile-based copolymer solid-solid phase change material from the second monomer, and a method for preparing an energy-storage and temperature-adjustment fiber / film from the phase change material prepared from the second monomer. The second monomer is prepared by the steps of enabling polyoxyethylene alkyl ether to react with sodium in methylbenzene, then enabling the reactant to react with an allyl monomer containing acyl chloride groups to obtain a crude product, and washing and carrying out liquid separation on the crude product. The acrylonitrile-based copolymer solid-solid phase change material prepared from the second monomer has the melting point being lower than the decomposition temperature and is applicable to melt spinning. The fiber / film with favorable energy-storage and temperature-adjustment performances can be prepared by mixing the acrylonitrile-based copolymer solid-solid phase change material with a thermal stabilizer and then spinning and filming under molten conditions.

The invention discloses a thermoplastic cellulose-based solid-solid phase transition material and a preparation method thereof. The preparation method comprises the following steps: 1, drying cellulose or a cellulose derivative; 2, respectively dissolving a cross-linking agent and polyethylene glycol alkyl ether in an organic solvent I to obtain a cross-linking agent solution and a polyethylene glycol alkyl ether solution, adding the polyethylene glycol alkyl ether to the cross-linking agent solution in a dropwise manner, adding a catalyst, and reacting for 0.5-10h to obtain a prepolymer solution, wherein a mole ratio of the polyethylene glycol alkyl ether to the cross-linking agent is 1:1; and 3, dissolving cellulose in an ionic liquid to obtain a cellulose solution, adding the prepolymer solution, acid anhydride and a catalyst to the above obtained cellulose solution, carrying out a polymerization reaction for 2-24h to obtain a finally obtained mixture, adding the finally obtained mixture to deionized water or an organic solvent II for precipitation, repeatedly washing the above obtained precipitate with deionized water 2-3 times, and carrying out vacuum drying to obtain the thermoplastic cellulose-based solid-solid phase transition material. The phase transition material has a good thermal stability and a melting processing performance, and can be blended with a thermoplastic copolymer matrix for melting processing.

A bondable blood-friendly polymer is a terpolymer or a quadripolymer at least formed by polyethylene glycol alkyl ether acrylate or polyethylene glycol alkyl ether methacrylate (I), and zwitterionic acrylic ester or zwitterionic methacrylic ester (II), and acrylic acid or a methacrylate derivative with an epoxypropyl group, an isocyanate group, a trialkoxy silane, a hydroxyalkyl group, a propargyl group or a quaternary ammonium group (III). In the present invention, the blood-friendly polymer with a potentially-bondable group has the following advantages: although the water insolubility thereof is implemented by using the hydrophobicity physical effect of an existing higher alkyl acrylate linkage, the blood friendliness of a coating is reduced due to the existence of a great number of hydrophobic chain links in the polymer; and a physical coating is slowly desolventized from the surface to be ablated in the application process of the physical coating. A disclosed bondable blood-friendly polymer coating not only can overcome these defects, but also can improve the blending property thereof. Disclosed are composition, a structure and a preparation method of the bondable blood-friendly polymer.
