Conclusions
1. The authors have studied the product of the reaction of formaldehyde with cellulose xanthate under the conditions of polynosic fibre forming plants.
2. It is shown that during this reaction formaldehyde is added on to all the thiocarboxylic groups in the fibre.
3. It has been established that during the reaction of formaldehyde with the decomposition products of viscose in the coagulation bath, mainly sulphonated analogues of polyhydroxymethylene glycols are formed.
