Cross-linking in spinning solutions in the presence of a liquid disperse phase

The study of kinetics of formation of interfacial layers on the cellulose triacetate in methylene chloride-aqueous solution of albumin interface and phase separation in the presence of a protein-containing liquid disperse phase showed that particles of the disperse phase showed that particles of the disperse phase can be additional cross-linking sites as a result of association of macromolecules of the fibre-forming polymer near the phase boundary. A sharp increase in the viscosity of dispersions based on a solution of cellulose triacetate in methylene chloride was revealed when polyethylene oxide was incorporated in the protein-containing disperse phase. A mechanism of formation of the interfacial adsorption layer in the presence of protein and polyethylene oxide was proposed. It was shown that incorporation of compounds adsorbed om the phase boundary in both the disperse phase and the dispersion medium affect phase separation.
