The reactant solutions were pumped into tubular reactor by proportioning pumps.After reacting for a predetermine time in the reactor,the reaction solution was sprayed to form drops in the pressure inj ection de-vice.And then,the drops completed the polymerization reaction and were dried in the continuous phase which was heated in advance.The KSAP granules were prepared in this way.The optimized products which give an absorbency of 411g/g and whose average diameter was 1.65mm were obtained by the following condition.The mass ratio of cross linker and initiator to KGM was 0.29 and 0.45,respectively.The inner diameter of the tu-bular reactor was 4mm meanwhile the length of the reactor was 36m (reactive time was 25min).The reactor was heated to 78℃.The pressure offered by the pressure injection device was 0.7MPa.The continuous phase was polyethylene glycol-600(PEG-600).The temperature of the continuous phase was 80℃.
