ABSTRACT:
The invention relates to a new polyacrylamide adhesive suitable for the fixing of fine-particle sorbent layers based on organic and/or inorganic compounds, used in overpressured one- and multilayer chromatographic procedures.
The said adhesive is prepared by polymerizing the aqueous solutions of acrylamide and N,N'-methylene-bis-acrylamide in the presence of a catalyst pair at from 21.degree. to 30.degree. C., pulpifying the precipitate thus obtained and repeating the precipitation and the pulpification more times.
