Cooling Ethylene-vinyl alcohol

The effect of sorbed water, fast cooling of nylon 6 melt and addition of copolymer of ethylene and vinyl alcohol to nylon 6 on CP/MAS NMR spectrum and C Ti was studied [16]. It was found that sorbed water does not affect the spectra and the Tj values. However, differences could be observed between the spectra and Ti values of nylon 6 powder, nylon 6 film and nylon 6 in the blends. [Pg.456]

The control of temperature is obtained by stirring the dispersed phase and cooling the walls of the reactor. The size of the particles or beads formed is determined by the effectiveness of the stirring and by the presence of water-soluble suspending agents such as poly(ethylene oxide), poly(vinyl alcohol), hydroxypropylcellulose, and so on, and surfactants (represented by o-in Figures 8.8 and 8.9) the polymer serves to increase the viscosity of the medium and the surfactant (in low proportion) to improve the stabilization of the particles. [Pg.305]
