Journal ArticleDOI
Polybenzoxazoles and polybenzothiazoles
TL;DR: In this paper, a solution polycondensation of 3,3′-dihydroxybenzidine dihydrochloride with both aromatic and aliphatic dicarboxylic acids in polyphosphoric acid is described.
Journal ArticleDOI
Far-infrared spectra of polyalanines with α-helical and β-form structures
TL;DR: In this paper, the far-infrared spectra of poly-L-alanines having the α-helical conformation and the β-form structure were measured, showing strong dichroism parallel to the direction of stretching.
Journal ArticleDOI
Copolymerization of methyl methacrylate with glycidyl methacrylate and the reaction of the copolymer with amines
TL;DR: In this paper, the copolymerization of methyl methacrylate with glycidyl methcrylate and the kinetic of the reaction of copolymers with secondary amines were investigated.
Journal ArticleDOI
Syntheses of aromatic polyketones and aromatic polyamide
TL;DR: In this paper, a high molecular weight aromatic polyamide was derived from the polyketone obtained through Schmidt reaction or Beckmann rearrangement, which was found to have some regularity in an arrangement of its repeating units.
Journal ArticleDOI
Synthesis of polybenzimidazoles with sulfonic acid groups
TL;DR: In this article, 2-Sulfoterephthalic acid and disulfoisophthalic acid (DSIA) were synthesized through the sulfonation and the oxidation of m- and p-xylene.
