AbstractPoly(ethylene oxide/polylactide/poly(ethylene oxide) (PEO/PL/PEO) triblock copolymers, in which each block is connected by an ester bond, were synthesized by a coupling reaction between PL and PEO. Hydroxyl‐terminated PLs with various molecular weights were synthesized and used as hard segments.

The micellization properties of carboxy-modified Pluronics P85 (poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) (PEO-PPO-PEO) triblock copolymers) are investigated by means of a molecularly realistic self-consistent-field theory. We consider the, so-called, carboxylic acid end-standing P85 (CAE-85) case where the carboxylic group is ...

Characterization of an hyaluronic acid (HA)-poly(ethylene oxide) (PEO) hydrogel was performed by changing the number of side arms in a PEO molecule. Verification of grafting chemistry and mechanical strength, as well as swelling behaviors and surface morphologies of the HA-PEO hydrogels were analyzed by employing different x-linking molecular weights ...

The MARTINI coarse-grain (CG) force field is extended for a class of triblock block copolymers known as Pluronics. Existing MARTINI bead types are used to model the non-bonded part of the potential while single chain properties for both homopolymers, poly(ethylene oxide) (PEO) and poly(propylene oxide) (PPO), are used to develop the bonded interactions.

The amphiphilic character of triblock-copolymers made of poly(ethylene oxide) (PEO) and poly(propylene oxide) (PPO) changes substantially as a function of temperature. This leads to interesting phase behaviour when the block-copolymers are dissolved in water: micelle formation above a critical temperature and critical concentration, and an apparent ...

Structure of poly(ethylene oxide) complexes. II. Poly(ethylene oxide)–mercuric chloride complex
Journal of Polymer Science Part A-2: Polymer Physics, 1968AbstractThe structure of the crystalline complex of poly(ethylene oxide) with mercuric chloride, whose composition is (CH2CH2O)4 · HgCl2, has been determined by x‐ray diffraction. The unit cell is orthorhombic with the dimensions of a = 13.55 Å, b = 8.58 Å, and c (fiber axis) = 11.75 Å, and the unit cell contains 4 HgCl2 molecules and 16 CH2CH2O units.
