Polymer containing chelating groups, process for preparing it and its use in water purification |
| abstract |
Water insoluble polymers containing hydrophilic pendant moieties ending with a chelating group are disclosed. The polymers are useful in the purification of water polluted by heavy metals such as mercury and lead. The polymers have the general formula P-(-(-O-R)n-(NH-Q)p-F)m where P is a polymeric matrix capable of reacting with a polyalkylene glycol or an alkylene oxide having such a structure and molecular weight as to be insoluble in water; R is either -CH2CH2- or mixtures of -CH2CH2- and -CH2CH(CH3)-, with the molar ratio of both units in the mixture being at least 3:1; n is 3 to 50; m is a numeral such that the % by weight of all of the -(-(-O-R-)n(NH-Q)p-F hydrophilic chains is higher than 1% by weight of the total weight of (I); Q is a C2-C6 difunctional aliphatic or aromatic hydrocarbon radical; p is 0 or 1; F is a chelating group selected from dithiocarbamate and methyl-thiourea when p is 1, or from thiol and isothiouronium when p is 0. |
