    摘要: Silicate anchored multifunctional initiator has moiety initiating ring opening living polymerization of lactone or ethylene oxide or cyclic siloxane monomer and other moiety for initiating living free radical polymerization of ethylenically unsaturated monomer. The monomers are reacted with the initiator in a one-pot, one-step reaction to cause living polymerization of both monomers and exfoliation of silicate layers to provide dispersed block copolymer silicate nanocomposite, with the junction of the two blocks being anchored to silicate layer and each block dangling therefrom.

    摘要: Described herein, in the preferred embodiment, is a leonardite-based polyurethane resin binder that may be used, among other applications, as a binder in combination with foundry aggregate, e.g., sand, for molding or casting metal parts. The binders described herein comprise a humic substance, preferably leonardite, combined with a polymerizable polyol, an isocyanate, and a polymerization catalyst to make a polyurethane resin binder in situ in a foundry aggregate, such as sand. The lignite is mixed with the polymerizable polyol and dispersing agents as additives to improve the suspension quality and binder performance of the lignite-containing part of the binder components.
