Photo- and Thermoinduced Sol-Gel Transitions in Blends of Azobenzene Copolymers and Pluronic Surfactants
(2006-01)Novel self-assembling copolymers of 4-Methacryloyloxyazobenzene and NN-dimethylacrylamide (MOAB-DMA) exhibiting a pronounced photoviscosity effects in water are described. An optimum polymer architecture corresponding to ... -
Responsive Azobenzene-Containing Polymers and Gels
(2005-01)The photoviscosity effect in aqueous solutions of novel poly(4-methacryloyloxyazobenzene-co-N,N-dimethyl acrylamide) (MOAB-DMA) was demonstrated. The observed significant reduction in the zero-shear viscosity upon ... -
Rheological and Thermodynamic Properties of PEO-PPE-PEO and PAA-g-PEO-PPO-PEO System
(2003-01)Rheological and thermodynamic properties of Pluronic F127 copolymer and Pluronic-g-PAA have been studied as a function of temperature and concentration. A combination of rheometry and DSC was employed to examine the gelation ... -
Smart Microgel Studies. Interaction of Polyether-Modified Poly(Acrylic Acid) Microgels with Anticancer Drugs
(2003-01)Studies of submillimeter gels composed of covalently cross-linked poly(acrylic acid)-g-poly(ethylene oxide)-b-poly(propylene oxide)-b-poly(ethylene oxide) (Pluronic-PAA) networks are reviewed in light of potential applications ... -
Synthesis and Aggregation Behavior of Pluronic F87/Poly(acrylic acid) Block Copolymer with Doxorubicin
(2005-01)Poly(acrylic acid) (PAA) was grafted onto both termini of Pluronic F87 (PEO₆₇-PPO₃₉-PEO₆₇) via atom transfer radical polymerization to produce a novel muco-adhesive block copolymer PAA₈₀-b-F₈₇-b-PAA₈₀. It was observed that ... -
Synthesis and Properties of Novel Cationic, Temperature-Sensitive Block-Copolymers
(2004-01)Facile, one-step synthesis of self-assembling, cationic block copolymers of poly(2-N-(dimethylaminoethyl) methacrylate) (pDMAEMA) and PEO-PPO-PEO (Pluronic®) is developed. The copolymers are obtained via free-radical ... -
Titration Microcalorimetry Study: Interaction of Drug and Ionic Microgel System
(2004-01)Doxorubicin (DOX) and Pluronic-PAA interaction was investigated using isothermal titration calorimetry (ITC). DOX/polymer interaction is governed primarily by electrostatic interaction. The uptake of DOX results in the ...
