“…The experimentally lower molecular weight observed for these polymers are most likely related to the lower activity of the endo isomer of the norbornene toward polymerization . However, the increasing size of the dendrons may also shield the polymerizable group and result in lower molecular weights as observed for other systems . We were unable to calculate the theoretical molecular weight at the given conversions due to the overlapping peaks of the monomer and polymer in the 1 H NMR spectra.…”

The preparation and characterization of a series of first to fourth generation dendronized poly-(norbornene)s are presented. The monomers were synthesized in a divergent fashion from 5-norbornene-2-methanol, utilizing the acetonide protected anhydride of 2,2-bis(methylol)propionic acid. The norbornenyl bearing dendrons were polymerized by ring-opening metathesis polymerization, and it was found that the Grubbs' first generation catalyst resulted in polymers with lower polydispersity compared to the materials obtained when employing the second generation catalyst. Two series of first to fourth generation polymers were characterized by DSC, SEC, and dynamic rheological measurements. In addition, it was found that the fourth generation material could form regular, porous membranes and birefringent fibers. The membranes were characterized with atomic force and optical microscopy. The birefringent fibers were analyzed with X-ray diffraction, polarized FTIR, and polarized optical microscopy.

Dendritic architectures based on bis-MPA: functional polymeric scaffolds for application-driven research

2013

Dendritic polymers are highly branched, globular architectures with multiple representations of functional groups. These nanoscale organic frameworks continue to fascinate researchers worldwide and are today under intensive investigation in application-driven research. A large number of potential application areas have been suggested for dendritic polymers, including theranostics, biosensors, optics, adhesives and coatings. The transition from potential to real applications is strongly dictated by their commercial accessibility, scaffolding ability as well as biocompatibility. A dendritic family that fulfills these requirements is based on the 2,2-bismethylolpropionic acid (bis-MPA) monomer. This critical review is the first of its kind to cover most of the research activities generated on aliphatic polyester dendritic architectures based on bis-MPA. It is apparent that these scaffolds will continue to be in the forefront of cutting-edge research as their structural variations are endless including dendrons, dendrimers, hyperbranched polymers, dendritic-linear hybrids and their hybridization with inorganic surfaces.

“…Either route gives formal entrée to these “comb polymers” 1. Although both methods have been described and reviewed,2,3 we herein will be utilizing the latter procedure. Because of its abundance in nature, cellulose is a prime polymeric candidate4 that can be selectively dendronized to afford an easy avenue to tailored polymeric, chiral architectures, which are of utilitarian interest.…”

Summary: A series of regioselectively dendronized cellulose derivatives has been prepared by the treatment of cellulose in a N,N‐dimethylacetamide/LiCl solvent system with dendrons possessing isocyanate focal substituents. These new materials were characterized using FT‐IR and 13C NMR spectroscopies, and thermogravimetric analysis; the products were highly soluble in a wide range of organic solvents.
