    摘要： The invention relates to a method for producing paper with at least one fibrous material, a polymer, water and calcium oxide and/or calcium hydroxide, comprising the steps of disintegrating the fibrous material with water in a pulper for producing a fibrous material suspension and transferring the fibrous material suspension into a vat. The method is characterised in that in the disintegration of the fibrous material in the pulper calcium oxide and/or calcium hydroxide having a proportion of active substance between 0.1 kg per tonne of oven-dry fibrous material and 50 kg per tonne of fibrous material for setting of a pH value between 9 and 12 is added to the fibrous material suspension, and in the vat an acrylamide copolymer having a proportion of active substance between 0.1 kg per tonne of oven-dry fibrous material and 10 kg per tonne of fibrous material is added.
