    摘要： The preparation of polymers which contain pendant hydrophobic groups or a mixture of both pendant hydrophobic and alkoxylated groups is accomplished by reacting a preexisting polymer having pendant acid amide and/or carboxylic groups with a primary or secondary amine in a substantially homogenous reaction mixture, the amine reactant including the desired hydrophobic and alkoxylated radicals. A unique polymer, having both pendant hydrophobic and alkoxylated groups, is provided.
