Process for the preparation of alkylated N- or amino, ammonium or spirobicyclic ammonium group-containing, crosslinked polymer gels, which is characterized in that
a) in the crosslinkage step an aqueous solution of a polymer obtained by polymerization of the corresponding monomer is adjusted to a pH of 7.5-14 at a temperature of 0 to 90° C., then the appropriate crosslinking agent is metered in and precrosslinkage is carried out with stirring and the precrosslinked polymer is transferred for complete curing to a curing container, whereupon
b) the cured crude gel is cut into a defined shape, then
c) washed with methanol batchwise in a static or stirred bed and directly following this
d) in methanol, the alkylation is carried out, after which the alkylated gel
e) is first washed batchwise by means of methanol/NaCl washes in a static or stirred bed or continuously, then
f) batchwise by means of NaCl washes and final water washes with deionized water in a static or stirred bed or continuously and also a process for the preparation of the alkylators used in sted d).
制备含有烷基化N-或
氨基、
铵或螺环双环
铵基团的交联聚合物凝胶的过程,其特征在于:a)在交联步骤中,将通过相应单体聚合得到的聚合物的
水溶液调节至pH值为7.5-14,温度为0-90℃,然后加入适当的
交联剂,在搅拌下进行预交联,然后将预交联聚合物转移到固化容器中进行完全固化,b)将固化的原始凝胶切成定义的形状,然后c)分批用
甲醇在静态或搅拌床中进行清洗,直接在此之后d)用
甲醇进行烷基化,之后e)首先通过
甲醇/
氯化钠洗涤分批或连续洗涤烷基化凝胶,然后f)通过
氯化钠洗涤和脱离子
水静态或搅拌床或连续洗涤,同时提供用于步骤d)中使用的烷基化剂的制备方法。
