TL;DR: Preparation par deux methodes: 1) etherification par transfert de phase d'un polymere α,ω dielectrophile avec la p-hydroxyphenyl-2 oxazoline-2(I) 2) extension de chaine par transfERT de phase D'Un polymereα,ω diphenol avec le chlorure de methylene (II) ou polyetherification d'Un bisphenol in presence de (I).

TL;DR: In this paper, a method of polymerizing an alkene monomer to produce a polymer using a catalyst that is Cu(O), Cu2Te, CuSe, Cu2S, or a combination thereof, an initiator, and a component comprising a solvent and optional nitrogen-containing ligand, where the combination of the component and monomer is capable of diproportionating Cu(I)X into Cu (O) and Cu(II)X2 where X is Cl, Br, or I.

TL;DR: In this paper, the mesomorphic behavior of poly(methylsiloxane)s containing 4-methoxy-4'-hydroxy-trans-alpha-methylstilbene (4-n-PS) and 4-hydroxy -4'-methoxene-trans-, alpha-methyl-stilbenes (4'-n-ps) connected to the backbone by flexible spacers containing three, six and eleven (n = 3, 6, 11) methylene units, and some copolymers based on these two constitutional isomeric mes

TL;DR: In this article, the authors review recent work from our laboratory on structural principles and their use in the synthesis of thermotropic-lyotropic main chain liquid crystalline (LC) polyethers.

TL;DR: In this article, a cyclic trimeric liquid crystal above the uniaxial nematic-isotropic phase transition temperature was found to be linear in temperature, such that the quantity was less than 200 mK, where the supercooling limit of the isotropic phase.
