Poly high speed spinning

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]

We can successfully measure 170 MAS NMR spectra of poly(L-Ala)s using high-field and high-speed magic-angle spinning technique. From the 170 MAS spectra three kinds of NMR parameters such as chemical shift, quadrupolar coupling constant and asymmetric parameter were obtained exactly and understood the relationship... [Pg.133]
