Thermal properties of anionic polyurethane composition mixed with collagen product and hydrophilic sodium form of montmorillonite for use in the finishing of leather were studied by thermogravimetric method. The thermal indices of processes and thermo-oxidative destruction depending on the polyurethane were determined. influence anionic behavior chromium tanned gelatin films that imitate leather studied. APU natural compounds increases their stability both in air nitrogen atmosphere due to formation additional bonds between active groups APU, protein chrome tanning agent as result chemical reactions organic inorganic parts new structure formation. © 2016 Kauno Technologijos Universitetas.
