Nucleo-copolymers: oligonucleotide-based amphiphilic diblock copolymers
Chemical Communications, 2007For the first time, poly(butadiene) has been covalently linked to an oligonucleotide sequence and the resulting nucleo-copolymer exhibits amphiphilic properties in dilute aqueous solution, self-assembling into nanometer-sized vesicular structures.

Biodegradable block copolymers
Advanced Drug Delivery Reviews, 2001Recently, block copolymers have got tremendous impetus on the ongoing research in the area of drug delivery technology, due to their capability to provide a biomaterial having a broad range of amphiphilic characteristics, as well as targeting the drugs to specific site.

Thermoresponsive copolymer microgels
Journal of Materials Chemistry B, 2013Colloidal aqueous microgels have attracted notable attention due to their possible applications in both polymer chemistry and the (bio)material sector. Due to their soft internal network structure and their response to different external stimuli, they are suitable as carrier systems for different kinds of molecules (e.g.

Polyhydroxyalkanoates based copolymers
International Journal of Biological Macromolecules, 2019Polyhydroxyalkanoates (PHAs) belong to a family of natural polyesters and are produced under unbalanced growth conditions as intracellular carbon and energy reserves by a wide variety of microorganisms. Being biodegradable, biocompatible and environmental friendly thermoplastics, the PHAs are considered as future polymers to replace petrochemicals ...

Journal of the American Chemical Society, 2019
In this report, we merge block copolymers with vitrimers in an effort to realize the prospect of higher-order, nanoscale control over associative cross-link exchange and flow. We show the use of controlled polymerization as a vital tool to understand fundamental structure-property effects through the precise control of polymer architecture and ...

Miscibility Study in Fluorinated Tetrafluoroethylene Copolymer−Copolymer Blends
Macromolecules, 2001The miscibility of random fluorinated tetrafluoroethylene copolymers is investigated by differential scanning calorimetry (DSC) and X-ray diffraction (XRD). In particular, mixtures composed of poly(tetrafluoroethylene)-co-(hexafluoropropylene) (FEP) containing 1 mol % of comonomer and poly(tetrafluoroethylene)-co-(perfluoromethylvinyl ether) (PFMVE ...

Orienting Block Copolymer Microdomains with Block Copolymer Brushes
ACS Nano, 2012A simple, rapid, and robust technique for controlling the self-assembly of block copolymers (BCPs) with a large segmental interaction parameter, χ, is described using a surface modified with anchored BCP brushes. End-functionalized poly(styrene-b-ethylene oxide)s (PS-b-PEOs), where the fraction of PS (f(PS)) was varied, end-functionalized neat PS, and ...

Current Opinion in Solid State and Materials Science, 1999
The efficient synthesis of structurally well-defined block copolymers is exciting and important area of research. This article describes several methods for the preparation of di- and triblock copolymers. Examples are taken from the literature and include anionic, cationic, free-radical and metal-catalyzed polymerizations that are useful for the ...
