| 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 polymer is also provided, having both pendant hydrophobic and alkoxylated groups of the formula <CHEM> and <CHEM> wherein n is zero or an integer of from 1 to about 10, R min is a hydrophobic radical, R sec is an alkoxylated radical, and R<2> is hydrogen or a substituent other than hydrogen. |
