    摘要: A process for the preparation of an aminoethanol is described wherein an amine is vaporized in a collection vessel and the vapors are caused to pass upwardly through a defined reaction zone into a condensation zone where they are condensed and caused to flow downwardly into the reaction zone. In the reaction zone the flow toward the collection zone is retarded and, while retarded, epoxide reactant is directed thereagainst. The aminoethanol so formed is removed into the collection zone such as by directing condensed amine thereagainst.

    摘要: The present invention is directed to branched reactive water-soluble polymers comprising at least two polymer arms, such as poly(ethylene glycol), attached to a central aliphatic hydrocarbon core molecule through heteroatom linkages. The branched polymers bear at least one functional group for reacting with a biologically active agent to form a biologically active conjugate. The functional group of the branched polymer can be directly attached to the aliphatic hydrocarbon core or via an intervening linkage, such as a heteroatom, -alkylene-, —O-alkylene-O—, -alkylene-O-alkylene-, -aryl-O—, —O-aryl-, (—O-alkylene-)m, or (-alkylene-O—)m linkage, wherein m is 1-10.
