Abstract
The invention relates to amino group-containing polymers, which are produced by the polymerization of acrylates with aminoacrylates in the forms of esters of acrylic or methacrylic acid with amino alcohols. Polymers of this type are insoluble in the neutral to basic aqueous medium, but are soluble in the acid medium. They are particularly suitable for the production of colostomy bags.
