| abstract | 1,269,807. Cross-linked vinyl pyrrolidone polymer beads. GAF CORP. 6 June, 1969 [12 June, 1968], No. 28687/69. Headings C3C and C3P. [Also in Division C6] Porous, cross-linked beads or granules of a vinyl pyrrolidone polymer are obtained by polymerizing a mixture of vinyl pyrrolidone and a cross-linking monomer in an aqueous solution of an electrolyte and in the presence of a freeradical initiator, at 50‹ to 80‹ C. In examples, vinyl pyrrolidone is copolymerized with methyl- ene-bis-acrylamide, or ethylene-, tetraethylene- or polyethylene-glycol dimethacrylate, in the presence of, as electrolyte, Na 2 SO 4 or NaCl solution, and also Na 2 HPO 4 , and in some cases ethanol.n[GB1269807A] |
