Some peculiarities of the copolymer precipitation in spinning a strongly-acid chemisorptive fibre
- 13 Downloads
The existence of polyelectrolyte swelling (self-elongation of the fibre on change of medium) has been established in strongly acid undrawn gel-fibre.
It has been shown that cementing of the strongly-acid fibre after drying, when the fibre has been wet-spun into aqueous-organic baths, is caused by the presence of solvent which is strongly retained on the fibre.
A possible mechanism for the retention of solvent by the strongly-acid gel-fibre has been advanced.
