  • Patent number: 10882569
    Abstract: A vehicle body reinforcing structure includes: a panel-shaped reinforcing member having a through-hole penetrating through the reinforcing member in a plate-thickness direction of the reinforcing member and located inside a closed-section structure of a vehicle body framework portion; a first panel located at a position closer to an outside of the vehicle than the reinforcing member is; a second panel constituting the closed-section structure with the first panel and located at a position closer to an inside of the vehicle than the reinforcing member is; and a foaming adhesive member filled in an internal space of the closed-section structure, wherein the first panel and the second panel are bonded to each other by the foaming adhesive member penetrating through the through-hole of the reinforcing member, and the foaming adhesive member is filled between the first panel and the reinforcing member and between the second panel and the reinforcing member.

  • Publication number: 20130133516
    Abstract: The present invention provides a polymer brush-type filler which contains polymer chains at a high density and with a broad molecular weight distribution. Specifically, the present invention provides fine particles for chromatography comprising graft polymer chains obtained by grafting polymer chains via polymerization initiating groups on the surface of solid particles, wherein the graft polymer chains include specific repeating units, have a specific number average molecular weight and a specific molecular weight distribution and also have a high density of 0.03 chains/nm2 or more and 0.70 chains/nm2 or less.

  • Publication number: 20060036037
    Abstract: Thermoplastic molding compositions, comprising: A) at least one rubber-free copolymer in which no hydroxyl group, acid group, amino group, or anhydride group is present, based on at least one vinylaromatic monomer (a1) and at least one comonomer (a2), B) at least one rubber-free polymer in which at least one hydroxyl group, acid group, or amidno group is present, C) from 3 to 50% by weight, based on the total weight of the molding composition, of at least one rubber, D) at least one terpolymer, C)obtainable from d1) at least one vinylaromatic monomer, d2) at least one C1-C4-alkyl (meth)acrylate or (meth)acrylonitrile, and d3) from 0.4 to 4% by weight, based on the total weight of the teruolymer, of at least one monomer in which an ??-unsaturatedl anhydride is present, and E) at least one compound having at least two isocyanate groups.
