研究了异氰酸酯指数以及纤维素接枝丙烯酸类吸水剂的加入时间及用量等因素对材料性能的影响。

The influence of isocyanate indexes and the time of adding cellulose-acrylic acid graft water absorbent to resin properties were studied.

因此，认为纤维素和聚丙烯腈在非晶区具有一定的相容性。

Then, we consider that the cellulose and polyacrylonitrile are somewhat compatible in their amorphous area.

FTIR分析表明，吸水树脂是纤维素和丙烯酸的接枝共聚物。

FTIR shows the water absorbent resin is graft copolymer of cellulose and polyacrylate.
