    • The invention relates to a super-absorbent polymer (SAP) with anionic and/or cationic properties, and a time-delayed swelling action generated by polymerisation of ethylenically unsaturated vinyl compounds. Said SAP is characterised in that the swelling thereof begins after a minimum of 5 minutes and is generated by means of at least one method variant selected from the following: a) polymerisation of the monomer constituents in the presence of a combination consisting of at least one hydrolysis-stable cross-linker and at least one hydrolysis-labile cross-linker; b) polymerisation of at least one permanently anionic monomer and at least one hydrolysable cationic monomer; c) coating of a core polymer component with at least one other polyelectrolyte as a sheath polymer; and d) polymerisation of at least one hydrolysis-stable monomer with at least one hydrolysis-labile monomer in the presence of at least one cross-linker. Due to the difference between the three production alternatives in terms of starting materials and method conditions, and also as a result of the possibilities of combining said alternatives, super-absorbent polymers according to the invention can be obtained, that are especially suitable for use in foams, moulded bodies and fibres, and also as carriers for agents regulating plant and fungal growth, and for the controlled release of active substances, or in construction materials. The polymers are especially suitable for using as construction material additives.
    • 还要求保护的是超吸收性聚合物(SAP)具有阴离子和/或阳离子性能,和延迟溶胀作用,这是由烯属不饱和乙烯基化合物的聚合来制备。 该SAP的特征在于,其溶胀至少5分钟后开始,并且,它已经使用至少一个过程变体中,从该系列中的选择的)中的组合的存在下由至少一种水解稳定和至少一种水解不稳定的交联剂的单体成分的聚合而制备 ; b)中聚合至少一种永久阴离子单体和至少一种可水解的阳离子单体; c)中涂覆具有至少一个另外的聚电解质作为壳聚合物的核聚合物组分; D)聚合中的至少一种交联剂的存在下含有至少一种水解不稳定的单体的至少一种水解稳定的单体。 由于原料的三个制造替代品和工艺条件相对于还因为彼此可能组合都配备有本发明的,的可变性,可用的超吸收性聚合物,其特别适用于在泡沫,模制品和纤维的使用,也可作为植物和真菌生长的支撑 -regulating装置以及用于活性成分的或在建筑材料受控释放是合适的。 特别是,用作本发明的聚合物的建筑材料添加剂也是合适的。
