The reaction of sodium sulfide with either 1,4-dibromobut-2-ene 1 or 1,4-dibromobutane 2 has been carried out in presence of a phase transfer catalyst and it was observed that the former yields polymer, whereas the latter gives cyclic and linear products. Interestingly, trans/cis ...

% 1,4-butenylene units of the formula CH 2 —CH═CH—CH 2 and d) from 0 to 60 wt. % 1,4-butylene units of the formula CH 2 —CH 2 —CH 2 —CH 2 are outstandingly suitable for the production of rubber molded bodies of any kind, especially for the production of industrial ...
Two novel membranes were prepared on the basis of polyheteroarylene with 2,2′-biquinoline-6,6′ units and its complex with Cu(I). The polymer was synthesized with the use of a new bifunctional monomer [2,2′-biquinoline]-6,6′-diyldimethanamine obtained from the corresponding dicarbaldehyd...
Identical polymer couplings were attempted, but no product was observed in any case. It was decided that a different type of ene compound should be used, so maleimide was investigated as a potentially more active alternative to (meth)acrylamide. Maleimide-functionalised DNA (s0-Mal) was not ...
