WATER ABSORBENT POLYMERS AND A PROCESS FOR THEIR PREPARATION |
| 摘要 |
Water absorbent polymers and a process for their preparation are disclosed. The process for preparing water absorbent polymers comprises preparing a slurry with relatively high amounts of polymer particles (in the range of 40 to 55 wt % of the total mass of the slurry) having water absorbed therein. The slurry is then directly spray dried to obtain water absorbent polymers. |

1. A process for preparing a water absorbent polymer, said process comprising the following steps:
i. preparing by inverse suspension polymerization, a slurry comprising polymer particles having water absorbed therein, wherein said polymer particles are present in an amount ranging between 40% and 55% of the total mass of the slurry; ii. homogenising the slurry with the help of heat and stirring, to obtain a homogeneous slurry; and iii. spray drying the homogeneous slurry in a spray drier to obtain water absorbent polymer particles. |
