“…† Note that the dispersity of the molar mass distribution is nearly 2 for the copolymers obtained by copolymerization, but is systematically less (approximately 1.5) for the copolymers synthesized by cross-metathesis. Such distribution narrowing, which we also noted for other systems, 54,55,68 can presumably be explained by a loss of low-molar-mass chains during polymer isolation by precipitation. The fraction of such chains is non-negligible for a cross-metathesis product that possesses relatively low average molar mass and exponential distribution in chain length.…”

“…Solution properties of PCO were examined by static light scattering (SLS) and dynamic light scattering (DLS) in previous studies. 51,68 A rather high value of the second virial coefficient, A 2 = (2.4 ± 0.1) × 10 −3 mol m 3 kg −2 , and single-chain scattering behavior up to the concentration c = 30 g L −1 (at M w = 120 kg mol −1 ) indicates that chloroform is a good solvent for this polymer, and additionally, PCO is insoluble in ethyl acetate.…”

Effect of Chain Structure on the Various Properties of the Copolymers of Fluorinated Norbornenes with Cyclooctene

et al. 2023

Fluorinated polymers are attractive due to their special thermal, surface, gas separation, and other properties. In this study, new diblock, multiblock, and random copolymers of cyclooctene with two fluorinated norbornenes, 5-perfluorobutyl-2-norbornene and N-pentafluorophenyl-exo-endo-norbornene-5,6-dicarboximide, are synthesized by ring-opening metathesis copolymerization and macromolecular cross-metathesis in the presence of the first- to third-generation Grubbs’ Ru-catalysts. Their thermal, surface, bulk, and solution characteristics are investigated and compared using differential scanning calorimetry, water contact angle measurements, gas permeation, and light scattering, respectively. It is demonstrated that they are correlated with the chain structure of the copolymers. The properties of multiblock copolymers are generally closer to those of diblock copolymers than of random ones, which can be explained by the presence of long blocks capable of self-organization. In particular, diblock and multiblock fluorine-imide-containing copolymers show a tendency to form micelles in chloroform solutions well below the overlap concentration. The results obtained may be of interest to a wide range of researchers involved in the design of functional copolymers.

Functionalized polynorbornenes are very important specialty materials for a wide variety of practical and industrial applications. In the membrane technology field, polynorbonene derivatives play a main role in gas transport since they can be systematically and easily functionalized, thus affecting the membrane performance in gas separation processes. Thus, several methodologies have been employed to yield macromolecular architectures with tailored gas permeation properties. This review is intended to provide different synthesis routes of substituted polynorbornenes as well as the effects of the polymer chemical structures on their gas permeation properties, among others.
