EO-PO copolymers

It is important to recognize that the following analytical methods essentially determine EO-PO ratio ( H NMR, IR, cleavage methods) or even simply alkylene oxide content (compleximetric methods) of the analyte, and as such are not specific quantitative or qualitative methods for poloxamers, since EO-PO copolymers of a different structure (for instance, random copolymers, or PO-EO-PO block copolymers) may respond to the methods in a way indistinguishable from poloxamers. The principal technique that permits definitive identification of a sample as a poloxamer is C NMR, which allows structural details, such as the distribution of EO and PO units along the polymer chain, to be elucidated [10]. [Pg.767]

Nonionic surfactants, including EO-PO block copolymers, may be readily separated from anionic surfactants by a simple batch ion exchange method [21] analytical separation of EO-PO copolymers from other nonionic surfactants is possible by thin-layer chromatography (TLC) [22,23] and paper chromatography [24], and EO-PO copolymers may themselves be separated into narrow molecular weight fractions on a preparative scale by gel permeation chromatography (GPC) [25]. [Pg.768]

UCON is a random copolymer of ethylene oxide (EO) and propylene oxide (PO) and can be considered as a synthetic oil. POE is poly(oxyethylene), which is a homopolymer of EO. Random EO-PO copolymers are typical of synthetic oils used as lubricants in textile processing (53, 54). PLURONICS (BASE) are block copolymers of EO and PO. Both of these copolymers can be produced with viscosities ranging from that of a thin oil to that of a thick paste. Oils of appropriate viscosity give hydrodynamic lubrication in the high-speed spinning of synthetic fibers. The hydrophile-lipophile balance (HLB) in these polymers can be varied, by changing the EO-PO composition, to suit the aqueous solubility requirements. [Pg.3342]

To date there are thousands of products appearing in directories and patent literature. Generally, the compounds with EO/PO copolymers are exceptionally surface active and they migrate and spread readily at the interface. The fatty amines and quaternary cationics adhere to all surfaces including asphaltenes, resins, naphthenic acids, paraffin waxes, inorganic clays, carbons, and silica (288). [Pg.581]
