<p>PCT No. PCT/EP97/02768 Sec. 371 Date Nov. 23, 1998 Sec. 102(e) Date Nov. 23, 1998 PCT Filed May 28, 1997 PCT Pub. No. WO97/49754 PCT Pub. Date Dec. 31, 1997The 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. 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.</p> |
