Abstract
The in-plane order of Langmuir-Blodgett multilayers of a poly(4-vinylp yridine) quaternized with n-docosyl bromide has been studied by grazin g incidence X-ray diffraction. Strong evidence has been found for inte ractions of the alkyl side chains of the polymer molecules in neighbor ing layers, and an in-plane packing structure has been derived. Quanti tative analysis of the X-ray diffraction shows that strain disorder ra ther than domain size is the principal source of X-ray line broadening in this system.
