Block copolymers consisting of methyl vinyl ether (MeVE) units and octadecyl vinyl ether (ODVE) units were synthesized using the cationic living polymerization technique. The polymerization of MeVE was initiated with the trimethyl silyl iodide/l,l-diethoxyethane/ZnI, system at -40Β°C in toluene and t
## Abstract A new series of chiral liquidβcrystalline poly(vinyl ether)s was synthesized by cationic polymerization of the corresponding vinyl ether monomers. They consisted of a biphenyl mesogenic unit bearing an __(S)__β2βmethylbutyl chiral substituent and spaced via an alkyl segment of varying n
High molecular-weight aromatic polyamides were obtained from 1,5-and 2,6-bis-(4'-carboxy-4-phenylenoxy-sulfony1)naphthalene by direct polycondensation reaction in N-methyl-2pyrrolidone with various aromatic diamines, using triphenyl phosphite and pyridine as condensing agents. The polymers were char
