NEW MATERIAL:The polymerizable compound of formula I (X is group of formula IIWformula IV; Y is H, ≤5C alkyl, ≤5C alkoxy, thioalkoxy, alkoxyalkoxy, thioalkoxyalkyl, ≤3N tert-amine, trimethylsilyl, trimethylsilyloxy, trimethylgermyl, Cl or Br; R is H, CH 3 or Cl; m and n are positive integer) and having a weight-average molecular weight of 200W10,000. n USE: A metal adsorbent. n PREPARATION: The compound of formula I can be produced by reacting lithiated vinyltoluene with a vinyl compound of formula CH 2 =CH-Z (Z is group of formula V or CR=CH 2 ) in a solvent. The reaction is carried out preferably by producing lithiated vinyltoluene by the reaction of lithium diisopropylamide with vinyltoluene in a solution and adding the vinyl compound to the reaction product. n COPYRIGHT: (C)1986,JPO&Japio |
