丙烯酸盐和丙烯酰胺共聚物的制备

Preparation of the Copolymer of Acrylic Salt and Acrylamide

以丙烯酸为原料 ,加入少量丙烯酰胺和矿物盐 ,用偶氮二异丁腈为引发剂速聚而成一种新型增稠剂。并将其性能和印染效果与藻朊酸钠作了对比。结果表明 ,该增稠剂增稠效果与藻朊酸钠相当 。

This work mainly studies a kind of novel thickener with acrylicacid as raw material and azobisisobutyronitrile as initiator,which produced by joining a small quantity of acrylamide and mineral salts and rapidly aggregating. Its performances and effect for printing and dyeing are compared with those of sodium alginate, and its thickening effect is found to be equal to that of sodium alginate. The structure of the product is studied using IR spectrum.
