Molecular-weight distribution of cellulose triacetate and the strength of fibres and films

Conclusions The effect of the molecular-weight composition of CTA on the physicomechanical properties of films and yarns has been examined.The possibility of processing a mixture containing an addition of high-molecular CTA into fibre has been demonstrated.An increase in the strength of yarns and films containing an additive of high-molecular CTA has been established.Saratov State University.

Procedure for the polarographic determination of bound formaldehyde content in cellulose acetates

Conclusions -- A procedure has been developed for the polarographic determination of the bound formaldehyde content of cellulose acetates prepared by the high-temperature homogeneous cellulose acetylation method involving the use of a cross-linking agent.-- The use of this procedure is recommended for determining the bound formaldehyde content of cellulose acetates from various production operations and also in acetate fibres.Translated from Khimicheskie Volokna, No. 5, pp. 58–60, September–October, 1991.
