    摘要: Dendrimeric compounds and polymers are also provided wherein the dendrimer core is derived from the Michael reaction products. The branching pattern of the core and the multiplicity of the Michael addition lead to flexibility in designing and synthesizing dendrimeric materials.The Michael addition products are from a reaction between primary amines and activated α,β-unsaturated compounds exemplified by diethyl methylenemalonate (DEMM). In various embodiments, the reaction proceeds with high yields in the absence of strong base or Lewis acid catalyst under mild reaction conditions. Depending on the state of steric hindrance in the amine, the reaction products are a double Michael addition product or a so-called vicarious Michael addition reaction product.

    摘要: A polymer-carbon sorbent for removing carbon dioxide, heavy metals and toxic materials from a flue gas from a combustion process, such as coal-fired power plants, is described. The sorbent comprises a carbonaceous sorbent material and a cured amine-containing polymer, and sulfur. The polymer-carbon sorbents are formed by curing a curable amine-containing polymer in the presence of the carbonaceous sorbent material, sulfur, a cure accelerator and, optionally, a cure activator. A convenient carbonaceous sorbent material is an activated carbon, and a convenient curable amine-containing polymer is an allyl-containing poly(ethyleneimine), having a number average molecular weight between about 1,000 and about 10,000. The polymer-carbon sorbents may contain sulfur in excess of an amount needed to cure the curable amine-containing polymer. Such polymer-carbon sorbents are shown to capture more mercury, in both elemental an ionic forms, compared to activated carbon and adsorb carbon dioxide.
