PEO-PPO-PEO triblok kopolimeri

Farmaceutski glasnik, 2005
PEO-PPO-PEO triblok kopolimeri pripadaju skupini simetričnih, amfifilnih, neionskih, makromolekulskih površinski aktivnih tvari. Građeni su od hidrofobnog središnjeg polipropilenoksidnog dijela (PPO) te postraničnih hidrofilnih polietilenoksidnih dijelova (PEO).

Aggregation Behaviors of PEO-PPO-ph-PPO-PEO and PPO-PEO-ph-PEO-PPO at an Air/Water Interface: Experimental Study and Molecular Dynamics Simulation

Langmuir, 2012
The block polyethers PEO-PPO-ph-PPO-PEO (BPE) and PPO-PEO-ph-PEO-PPO (BEP) are synthesized by anionic polymerization using bisphenol A as initiator. Compared with Pluronic P123, the aggregation behaviors of BPE and BEP at an air/water interface are investigated by the surface tension and dilational viscoelasticity.

PEO Flocculation with Phenolic Microparticles

Journal of Colloid and Interface Science, 2002
Polystyrene latex and precipitated calcium carbonate (PCC) with and without dextran sulfate pretreatment were flocculated by the consecutive addition of high-molecular-weight poly(ethylene oxide) and a novel composite latex microparticle consisting of a polystyrene core and a poly(p-vinylphenol) shell. Good flocculation of polystyrene latex and PCC was

PDMS−PEO Densely Grafted Copolymers

Macromolecules, 2005
Molecular brushes with poly(dimethylsiloxane) (PDMS) side chains were prepared by atom transfer radical polymerization (ATRP) conditions via macromonomer method (grafting through). The well-defined polymers with molecular weight distribution Mw/Mn = 1.22−1.35 and with up to 350 repeating units of macromonomers with methacrylate functionality (PDMSMA ...

Gelation behavior of PEO–PLGA–PEO triblock copolymers in water

Polymer, 2002
Abstract Aqueous solutions of poly(ethylene oxide-b-( dl -lactic acid-co-glycolic acid)-b-ethylene oxide) with two different molecular weights (550–3.4K–550 and 750–3.5K–750) show the change in turbidity as a function of temperature. The variation in turbidity is also found to be independent of block copolymer concentration.

PEO-PPO-PEO triblock copolymers and their biomedical applications

2006
Thermoreversible polymeric systems represent an interesting class of materials that can be tailored for a wide range of application. PEO-PPO-PEO copolymer systems show thermoreversible gelation around body temperature and therefore are of particular interest for biomedical applications such as drug delivery, gene therapy and tissue engineering. PEO-PPO-
