A process for the preparation of superabsorbent polymer containing clay, the process including the steps of (I) polymerizing a polymerization mixture comprising: (a) one or more ethylenically unsaturated carboxyl-containing monomers, (b) one or more crosslinking agents, (c) optionally one or more comonomers copolymerizable with the carboxyl-containing monomer, (d) neutralizing agent to partially neutralize the polymer to from about 50% to about 99%, by weight, and (e) a polymerization medium, to form a crosslinked partially neutralized hydrogel, (II) admixing a clay with the crosslinked partially neutralized hydrogel to form partially neutralized superabsorbent polymer-clay hydrogel； (III) drying the crosslinked partially neutralized hydrogel at a temperature from about 190℃ to about 210℃ and for a time period of from about 15 minutes to about 120 minutes, and (IV) comminuting the dried partially neutralized superabsorbent polymer-clay hydrogel to particles.本發明係關於一種製備含有黏土之超吸收性聚合物之方法，該方法包括下列步驟：(I)使聚合混合物聚合以形成經部分中和之交聯水凝膠，該聚合混合物包含：(a)一或多種乙烯系不飽和含羧基單體，(b)一或多種交聯劑，(c)視情況選用之一或多種可與含羧基單體共聚合之共單體，(d)部分中和該聚合物至約50重量%至約99重量%之中和劑及(e)聚合介質，(II)使黏土與經部分中和之交聯水凝膠摻混以形成經部分中和之超吸收性聚合物-黏土水凝膠；(III)該經部分中和之交聯水凝膠在約190℃至約210℃之溫度下乾燥一段約15分鐘至約120分鐘之時間並(IV)將已乾燥經部分中和之超吸收性聚合物-黏土水凝膠粉碎成粒子。
