Abstract

See full text

The present invention relates to a process for the production of polymers, such as water-absorbing polymer structures, by radical polymerization of acrylic acid, whereby the acrylic acid has been obtained by a synthesis process which comprises as a process step the splitting of an organic material by means of an enzyme or at least one component of an enzyme. The invention also relates to the water-absorbing polymers obtainable by this process, water-absorbing polymers which are based to at least about 25 wt % upon partially neutralized acrylic acid, a composite, a process for the production of a composite, the composite obtainable by this production, the use of acrylic acid in the production of polymers, preferably in the production of water-absorbing polymer structures, a device for the production of acrylic acid, and a process for the production of acrylic acid.
