Reference of 11-Bromoundecanoic acid. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 11-Bromoundecanoic acid, is researched, Molecular C11H21BrO2, CAS is 2834-05-1, about Temperature-responsive star-shaped poly(2-ethyl-2-oxazoline) and poly(2-isopropyl-2-oxazoline) with central thiacalix[4]arene fragments: structure and properties in solutions.

Temperature-responsive star-shaped poly(2-ethyl-2-oxazoline) (star-PETOX) and poly(2-isopropyl-2-oxazoline) (star-PIPOX) with arms grafted to the lower rim of thiacalix[4]arene were studied in solutions by viscometry, sedimentation velocity, light scattering, and small-angle neutron scattering. The experiments were carried out in water and THF solutions It was revealed that in THF, the studied polymers were present only as individual mols., while in aqueous solutions, in addition to individual mols., large polymer aggregates were found. Mol. characteristics of the star-PETOX and star-PIPOX samples were estimated; their behavior in THF and water was studied over a wide temperature range. It was established that a cloud point of the aqueous solution of star-PETOX (67 °C) is higher than that of a solution of star-PIPOX (35 °C). Comparison of the data obtained by dynamic light scattering and small-angle neutron scattering turned out to be fruitful in revealing all the structural levels of the organization of star-PETOX and star-PIPOX in aqueous solutions They include the level of the individual macromols. and the level of supramol. organization with a star-like architecture.
