The invention relates to polyamides which are derivatized with polymerizable double bonds and are obtainable by reaction of the amino groups of the polyamide with an amino-reactive compound which contains a polymerizable double bond, or by reaction of the carboxyl groups of the polyamide with a carboxyl group-reactive compound which contains a polymerizable double bond. Examples of amino-reactive compounds which contain a polymerizable double bond are the anhydrides of ethylenically unsaturated carboxylic acids, such as acrylic acid chloride or anhydride, methacrylic acid chloride or anhydride, or vinylazlactone derivatives. An example of a carboxyl group-reactive compound is allylamine. n These derivatized polyamides can be converted into polymer-modified base polymers (typically block polymers) with improved properties. These polymer-modified base polymers are suitable as adsorbents for chromatography and as carriers for enzymes. |
