Ion-Conductive Properties of Propylene Carbonate/Propylene Oxide Copolymers

Intracellular delivery of VEGF165 encoding gene therapeutic using trifunctional copolymers of ethylene oxide and propylene oxide

Structural Polymorphism of Poly(ethylene oxide)-Poly(propylene oxide) Block Copolymers in Nonaqueous Polar Solvents

The solution properties of water-soluble amphiphiles in nonaqueous polar solvents are important in the elucidation of the effects of solvent quality on self-assembly and also in practical applications where the use of water as a solvent is undesirable. We studied the self-assembly of a poly(ethylene oxide)-poly(propylene oxide) (PEO-PPO) block copolymer (Pluronic P105: EO37PO58EO37) in formamid...

Poly(ethylene oxide)–Poly(propylene oxide)-Based Copolymers for Transdermal Drug Delivery: An Overview

Amphiphilic poly(ethylene oxide)–poly(propylene oxide) (PEO–PPO)-based copolymers are thermoresponsive materials having aggregation properties in aqueous medium. As hydrosolubilizers of poorly water-soluble drugs and improved stability of sensitive agents, these materials have been investigated for improvement in solubility, stability, release and bioavailability of drugs. The goal of the prese...

Two-Sided Comb Poly(amic ester)–Poly(propylene oxide) Graft Copolymers as Porous Polyimide Precursors

New step-growth graft block copolymers were synthesized. These two-sided comb copolymers consisted of a poly(amic ester) (PAE) backbone and pendant poly(propylene oxide) (PPO) grafts. The copolymers were made via a macromonomer approach, in which the 4,6-bischlorocarbonyl isophthalic acid bis[poly(propylene oxide)] ester macromonomer was synthesized through the reaction of hydroxyl-terminated P...

Propylene oxide as sterilizing agent.

Liquid propylene oxide added to a variety of disinfectant solutions resulted in a significant reduction of the bacterial spore content of these solutions.
