Chemistry And Technology Of Man-Made Fibres


A stable value of the surface tension, σ, of concentrated solutions of PPIP in DMAc is established over the course of several days after completion of the synthesis.

Heating leads to a marked increase in σ, which then relaxes to a steady value over a period of several days.

The value of σ also depends on the ratio of the components in the neutralizing mixture, diethylamine plus DMAc.
