    Abstract: Water-insoluble, tridimensional cross-linked random copolymers, which contain in copolymerized form:(a) 25% to 98% by weight of N-[tris(hydroxymethyl)methyl]acrylamide or N-[tris(hydroxymethyl)methyl]methacrylamide or a mixture of these two compounds;(b) 2% to 50% by weight of one or more monomers having several polymerizable ethylenic double bonds and one or more hydroxy groups, and free from NH.sub.2 or COOH groups; and(c) 0% to 50% by weight of one or more monomers having a polymerizable ethylenic double bond and one or more amino or carboxy groups. These copolymers may be used, in the form of aqueous gels, as supports in techniques of separation such as gell permeation chromatography and in techniques of immobilization of natural substances.

    Abstract: A process for preparing plates of a new gel polymer, said plates being adapted to the electrophoresis separation of the seric or plasmatic lipoproteins under a stepped gradient. The gel polymers are prepared by radical polymerization of N-methylol-acrylamide and of a bifunctional allylic or acrylic compound causing cross-linking to yield a tridimensional configuration polymer. The polymerization may optionally be catalyzed by peroxides and/or ultraviolet radiation. Anionic polysaccharides containing only COOH groups may be added to assist migration of lipoproteins in the gel.
