ポリビニルアルコール繊維のアクロレインによるアセタール化

抄録

The influences of temperature and aldehyde concentration over the reaction velocity in acetalizing PVA fibre with acrolein and the reaction velocity depending upon the diffusion velocity of reagent into fibre were sought. The degrees of swelling, tenacities and elongations of the fibres were measured, and found that this kind of treatment is of no use for particular improvement of mechanical properties of the fibre.
