    摘要: Covers a new composition of matter comprising a stable N-(.omega.-monoalkylaminoalkyl) acrylamide or methacrylamide monomer characterized by the following structural formula: ##STR1## where R.sub.1 and R.sub.2 are hydrogen or methyl, R.sub.3 is isopropyl or t-butyl and n is 2 or 3, with the proviso that when R.sub.1 is hydrogen, R.sub.3 is t-butyl. Also covers a method of preparing said monomer by condensing one mole of an acrylic or methacrylic compound with two moles of an appropriate amine to form an intermediate substituted amide, followed by heating said intermediate to split off one mole of reactant diamine leaving the desired substituted aminoalkyl acrylamide or acrylamide monomer.

    摘要: An improved process for selectively preparing a predominantly noncyclic polyalkylene polyamine compound is disclosed wherein an alkyleneamine compound is contacted with a diol compound in the presence of a catalytically effective amount of a phosphorus-containing substance at a temperature of from about 250.degree. to about 350.degree. C under a pressure sufficient to maintain the mixture essentially in liquid phase and the polyalkylene polyamine is then recovered from the resultant reaction mixture. In a preferred embodiment ethylenediamine is contacted with monoethylene diol to produce a predominantly linear polyethylene polyamine product with very low yields of heterocyclic amine materials. The desired polyethylene polyamines produced can be directly recovered from the reaction products by known purification procedures.
