Liquid crystalline polyethers based on conformational isomerism: 8. Synthesis and determination of the virtual mesomorphic phase transitions of polyethers and copolyethers based on 1-(4-hydroxyphenyl)-2-(2-methyl-4-hydroxyphenyl) ethane and 1,14-dibromotetradecane

TL;DR: In this paper, the polyethers prepare a partir de l'(hydroxy-4) phenyl-1 (methyl-2 hydroxy-4)-phenyl-2 ethane (MBPE) and du dibromo-1,4 tetradecane sont seulement cristallins alors que les copolymeres derives du meme MBPE and de melanges de dibrromotetradesdecane avec un autre α,ω-dibromoealcane montrent une mes

TL;DR: Magnetic and electrical Freedericksz measurements were performed on the second generation monodendritic liquid crystal G2(OH) as mentioned in this paper, and the deduced elastic constants were found to be exceptionally anisotropic: the splay elastic constant K11 is more than an order of magnitude larger than the bend elastic constants K33 and the twist constant K22 is approximately twice K33.
Journal ArticleDOI
The influence of molecular weight of the donor polymer on the solid-state behavior of interchain EDA complexes
TL;DR: In this article, the thermal behavior of homopolymers and their EDA complexes with poly(β-hydroxyethyl-3,5-dinitrobenzoyl methacrylate) (PDNBM-2) was studied as a function of molecular weight.
Journal ArticleDOI
On the polymerization of acetylenic derivatives. XIX. Synthesis of poly (α-ethynyl naphtalene) and its electrophysical properties
TL;DR: In this paper, the polymerization of α-ethynyl naphtalene with Ziegler soluble catalysts and tertiary phosphine-transition metal complexes has been investigated.
