摘要： The invention is relative to optionally cross-linked organopolysiloxane urea derivatives and thiourea derivatives consisting of: ##STR1## wherein X stands for 0 or S andR.sup.1 is a group of the formula: ##STR2## in which R.sup.5 is alkylene with 1 to 10 C atoms or cycloalkylene with 5 to 8 C atoms or a group of the formula: ##STR3## with n=1-6 (on the nitrogen)m=0-6 (on the silicon), wherein R.sup.2 has the same meaning as R.sup.1 or stands for H, R.sup.3 and R.sup.4 have the same meaning as R.sup.1 or stands for H or alkyl with 1 to 5 C atoms. At least two but at the most three groups according to formula (2) are bound to the units according to formula (1). The free valances of the oxygen atoms bound to the silicon atom are saturated by silicon atoms of further groups of formula (2) with the optional inclusion of cross-linking agents. In addition, preparative methods for the products and a use for the removal of dissolved metals from liquid phases are indicated.
摘要翻译：本发明相对于任选的交联的有机聚硅氧烷脲衍生物和硫脲衍生物，其由以下组成：其中X代表0或S，R1是下式的基团：其中R5是具有1至10个C原子的亚烷基或具有5至8个碳原子的亚环烷基或具有n = 1-6（在氮上）m = 0-6（在硅上的下式的基团：），其中R2具有与R 1相同的含义或代表H，R 3和R 4具有与R 1相同的含义或代表H或具有1至5个C原子的烷基。根据式（2），至少两个但最多三个基团与根据式（1）的单元结合。与硅原子结合的氧原子的自由价数由另外的式（2）基团的硅原子饱和，任选地包含交联剂。此外，还指出了产品的制备方法和用于从液相中除去溶解的金属的用途。
