摘要：
Provided is a method of preparing super absorbent polymer. The method comprising the steps of: preparing a hydrogel crosslinked polymer by polymerizing a monomer composition including hydrophilic monomers, a crosslinking agent and a polymerization initiator pulverizing the hydrogel crosslinked polymer drying the pulverized hydrogel crosslinked polymer preparing a base resin by pulverizing the dried hydrogel crosslinked polymer and mixing the base resin with at least one of compounds represented by Formula (1) below and a surface-crosslinking agent to surface-crosslink the base resin: X-(Ra)p(Rb)q-Y ---- (1)提供一種製備超吸收聚合物。此方法包含步驟:藉由使包括親水性單體、一交聯劑,及一聚合反應起始劑之一單體組成物聚合製備一水凝膠交聯聚合物;使水凝膠交聯聚合物粉碎;使經粉碎之水凝膠交聯聚合物乾燥;藉由使經乾燥之水凝膠交聯聚合物粉碎製備一基底樹脂;及使基底樹脂與以如下化學式(1)表示之化合物之至少一者及一表面交聯劑混合使基底樹脂表面交聯:X-(Ra)p(Rb)q-Y----(1)。P1‧‧‧製備單體組成物P11‧‧‧製備包括親水性單體及中和劑之第一組成物P12‧‧‧藉由使第一組成物與交聯劑及聚合反應起始劑混合製備第二組成物P2‧‧‧製備水凝膠交聯聚合物P3‧‧‧使水凝膠交聯聚合物粉碎P4‧‧‧使經粉碎之水凝膠交聯聚合物乾燥P5‧‧‧藉由使經乾燥之水凝膠交聯聚合物粉碎製備基底樹脂P6‧‧‧使基底樹脂表面交聯P61‧‧‧使基底樹脂與以如下化學式(1)表示之化合物之至少一者及表面交聯劑混合X-(Ra)p(Rb)q-Y----(1)P62‧‧‧使經表面處理之基底樹脂乾燥
