✦ Synopsis

X-ray structure analysis was carried out in order to clarify the crystal structure and structural disorder of poly-(p-phenylenebenzobisthiazole). Two molecular chains pass through an oblique unit cell with parameters a Ο­ 11.60 Γ…, b Ο­ 3.588 Γ…, β₯ Ο­ 92.0Β°and the plane group p2. The angle between the phenylene and benzobisthiazole rings was estimated as 20.5Β°. Poly-(p-phenylenebenzobisthiazole) includes the disorder with respect to the molecular height, because the first and third layer lines are diffuse streak. On the ac plane, the molecular heights are disordered by 1/2 because 102, 602, and 404 reflections can be observed. On the bc plane, the molecular heights are disordered by every 1/5 because the 015 reflection can be observed.

Polymerization of p-acetoxybenzoic acid between mica sheets, from both the melt and dilute solution, in a wide range of polymerization temperatures (180-400ЊC) yields an epitaxial-like overgrowth of PpOBA on the mica cleavage surface. The PpOBA overgrowth forms long rows by lateral aggregation of ri

## Abstract A new model based on disorder phenomenon concerning the symmetry is proposed for the crystalline structure of form II of poly(vinylidene fluoride) (PVDF). The disorder has the effect that the crystal possesses no unique space group but it consists alternately of monoclinic regions with
