Phase separations in a copolymer–copolymer mixture
Journal of Physics: Condensed Matter, 2005We propose a three-order-parameter model to study the phase separations in a diblock copolymer–diblock copolymer mixture. The cell dynamical simulations provide rich information about the phase evolution and structural formation, especially the appearance of onion-rings. The parametric dependence and physical reason for the domain growth of onion-rings

Polyethylene‐based polyurethane copolymers and block copolymers
Macromolecular Symposia, 1995AbstractLow molecular weight hydroxy terminated polyethylene (HTPE) containing on average an ethyl group every 16–18 carbon atoms, and a hydroxy functionality of 2.6, has been used to prepare polyurethane copolymers and block copolymers which have good solvent resistance. The polymers show somewhat complicated thermal behavior, including Tg's at around

Skin delivery by block copolymer nanoparticles (block copolymer micelles)
International Journal of Pharmaceutics, 2015Block copolymer nanoparticles often referred to as "block copolymer micelles" have been assessed as carriers for skin delivery of hydrophobic drugs. Such carriers are based on organic biocompatible and biodegradable materials loaded with hydrophobic drugs: poly(lactide)-block-poly(ethylene glycol) copolymer (PLA-b-PEG) nanoparticles that have a solid ...

ALTERNATING COPOLYMER GRAFT COPOLYMERS—XI. GRAFTING THROUGH MATRIX POLYMERIZATION
Pure and Applied Chemistry, 1976The comonomer complexes generated as a result of the interaction of a donor monomer and an acceptor monomer in the presence of a complexing agent are arrayed in the form of a matrix and undergo radical initiated homopolymerization to yield an alternating copolymer.

Graft Copolymer and Block Copolymer Surfaces
1985Homopolymers and random copolymers are relatively homogeneous in composition throughout their bulk. At the outermost molecular layer of such materials, the surface chemistry might differ substantially from the average bulk chemistry due to orientation effects, oxidation, or contamination.
