Poly(ethylene oxide)-poly(propylene oxide)–poly(ethylene oxide) ((EO)n–(PO)m–(EO)n) block copolymers, commercially available as Pluronics (BASF Corp.) and Poloxamers (ICI Corp.), have been widely applied in medicine, biochemistry, and other fields because of their ability to form reversible micelles and physical gels in aqueous solution. Generally, for

Abstract This study describes the toughening of poly(lactic acid) (PLA) through blending it with poly(ethylene oxide)–poly(propylene oxide)–poly(ethylene oxide) triblock copolymers (EPE, Pluronic®) at loadings less than 10 wt%. The miscibility of EPE copolymers in PLA was examined by thermal, morphological, and rheological analysis.

Crystallization of poly(ethylene oxide) in i-polypropylene-poly(ethylene oxide) blends
Journal of Applied Polymer Science, 1997A two-stage stable system of isotactic polypropylene-poly(ethylene oxide) blend, in which poly(ethylene oxide) can be permanent either in molten or in crystallized states in the temperature range from 280 to 327 K, was described. The behavior of that blend was explained in terms of fractionated crystallization.

Journal of Microencapsulation, 2004
A novel method for preparing the PLGA nanospheres with hydrophilic surface has been designed and characterized. Because of good solubility of tetraglycol in water, PLGA (poly(lactide-co-glycolide)) nanospheres were formed by spraying the PLGA/tetraglycol solution into water.

Abstract Blends of poly(ethylene) oxide with poly(epichlorohydrin) and poly(epichlorohydrin- co -ethylene oxide) havebeen prepared by the freeze-drying method from benzene solutions of the polymer mixture at different compositions. The miscibility of the mixtures was studied by DSC. A single glass transition temperature is observed for all the blends

Poly(ethylene oxide) blends with poly(ethylene oxide)/poly(dicyclohexyl itaconate) block copolymers
European Polymer Journal, 2001Abstract Blends of poly(ethylene oxide) and block copolymers poly(ethylene oxide)-block-poly(dicyclohexyl itaconate)s (PEO-b-PDCHI) with different molecular masses were prepared by solution casting from chloroform. Thermal properties and kinetics of nonisothermal melting and crystallization were studied using differential scanning calorimetry.
