The present invention relates to a process for the production of polymers, preferably water-absorbing polymer structures, by radical polymerisation of acrylic acid, whereby the acrylic acid has been obtained by a synthesis process which comprises as 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 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 srtuctures, a device for the production of acrylic acid, a process for the production of acrylic acid.本發明係關於一種藉由丙烯酸之自由基聚合反應製造聚合物,較佳係吸水聚合物結構物之方法,其中該丙烯酸已利用一種合成方法獲得,其中該合成方法包括以酶或至少一酶之組分分解有機材料之程序步驟。本發明亦關於可藉由此方法獲得之吸水聚合物、以至少25重量%經部分中和之丙烯酸為基質之吸水聚合物、一種複合物、一種用於製造複合物之方法、可藉由此方法獲得之複合物、丙烯酸在製造聚合物,較佳係在製造吸水聚合物結構物方面之用途、一種用於製造丙烯酸之裝置及一種製造丙烯酸之方法。1...生物反應器2...欲分離之有機材料的進料線3...第一純化裝置4...化合物貯槽5...蒸發器6...脫水反應器之觸媒床7...凝結裝置8...溶劑之進料線9...進一步加工丙烯酸之產物出口10...加熱元件
