Abstract:
The present invention relates to an interpenetrating polymer network (IPN) material comprising a copolymer of vinylamine-vinylformamide, and a homo-polymer or a copolymer of at least one monomer selected from acrylamide or derivatives thereof, acrylic acid or derivatives thereof, or a mixture thereof forming the IPN material together with the copolymer of vinylamine-vinyl-formamide. The present invention further relates to a process for producing the IPN material, and to use of the IPN material in paper industry.
