Journal ArticleDOI
Cationic bulk polymerization of vinyl ethers in the liquid crystalline phase
TL;DR: In this paper, Cationic bulk polymerization of liquid crystalline phenyl benzoate and biphenyl vinyl ethers was performed using either thermal or photochemical initiation by onium salts.
Patent
Soluble fluorinated poly-p-phenylenes
TL;DR: In this article, the precursors of poly-p-phenylenes have been identified and their copolymers and their substituents are discussed, which are useful as membranes, coatings, fibers and articles.
Journal ArticleDOI
Synthesis of Functional Aromatic Multisulfonyl Chlorides and Their Masked Precursors.

TL;DR: In this article, the synthesis of functional aromatic bis(sulfonyl chlorides) containing an acetophenone and two sulfonyl chloride groups was described, involving in the last step the quantitative oxidative chlorination of S-(aryl)- N,N'-diethylthiocarbamate, alkyl- or benzyl thiophenyl groups as masked nonreactive precursors.
Journal ArticleDOI
Crystallization behavior of polyethers containing odd numbers of methylene spacers from the isotropic and liquid crystalline states
TL;DR: In this paper, a series of thermotropic polyethers synthesized from 1-(4-hydroxyphenyl) - 2 - (2 - methyl - 4 - hydroxymhenyl)- ethane and α,ω-dibromo-n-alkanes with odd numbers of methylene units (MBPE-n = odd) was studied.
Journal ArticleDOI
Synthesis of aromatic polyethers by cation-radical polymerization
Virgil Percec,James H. Wang +1 more
TL;DR: In this article, the synthesis of polymers of unique structure by the cation-radical polymerization reactions has been studied under a variety of experimental conditions, including the effects of the monomer structure on the reactivity of both the monomers and of the Cation-Radial growing species, and an example in which the polymerization proceeds by both a cation radical reaction and an electrophilic transalkylation reaction is provided by the polymerisation of 2,2-bis[4-(1-naphthoxy)phenyl]propane initiated with Fe
