A substitute for amino and phenolic resins is disclosed. It is used in the polycondensation of such resins based on formaldehyde for bonding water penetrable cellulosic particles. The substitute comprises an aqueous solution of(a) either at least one aldehyde together with at least one amide and/or together with at least one phenol, or a non-resinous condensation product of formaldehyde and urea, and(b) a sugar or a sugar derivative or their byproducts or a starch or its degradation products or a mixture thereof, and/or(c) a raw and/or treated lignosulfonate.This substitute also reduces the free formaldehyde of the resulting board without impairing the other properties thereof.
摘要:
A resist underlayer film-forming composition has high solubility in a solvent used at a lithography process for exhibiting good coating film forming properties and able to decrease a sublime generated during formation of a film. A resist underlayer film-forming composition having a novolac resin having a structure group (C) obtained by a reaction of an aromatic ring structure of an aromatic ring-containing compound (A) with a vinyl group of an aromatic vinyl compound (B). The aromatic vinyl compound (B) is represented by Formula (1), and is specifically styrene, 2-vinylnaphthalene, 4-tert-butylstyrene, or 4-tert-butoxystyrene.
The structure group (C) is represented by Formula (2).
The aromatic ring-containing compound (A) is an aromatic amine compound or a phenolic hydroxy group-containing compound. The novolac resin is a resin produced by a reaction of the aromatic amine compound or the phenolic hydroxy group-containing compound with aldehyde or ketone.
摘要:
Method for manufacturing optically transparent gel-polymer electrolytes includes reaction of copolymerization of melamine and formaldehyde or melamine and glyoxal with one or several polyols and/or with one or several monosaccharides, oligosaccharides or polysaccharides and adding of a concentrated acid to form an optically transparent gel-polymer. The electrolyte according to the invention can be used in electrochromic devices and other optical-electrochemical devices as well as in devices for storing electrical energy (such as batteries, supercapacitors and hybrid power storage devices), thus replacing conventional water-based electrolytes.
摘要:
The present invention relates to a binder composition for making self-hardening foundry molds that is capable of improving the hardening speed of the molds and the strength of the molds, and is excellent in storage stability; and a method for producing a foundry mold, using this composition. The binder composition for making self-hardening foundry molds of the present invention is a binder composition for making self-hardening foundry molds, comprising a furan resin and an ion compound, wherein the ion compound contains at least one anion selected from the group consisting of a hydrogensulfite ion, a sulfite ion, a pyrosulfite ion, a thiosulfate ion, a thionate ion, and a dithionite ion; the content of the anion is from 0.006 to 0.60 parts by weight for 100 parts by weight of the furan resin; and the composition has a pH of 6 or less at 25° C.
