Investigation of Structure and Properties of Biodegradable Compositions of Polylactide with Ethyl Cellulose and Chitosan Plasticized by Poly(Ethylene Glycol)
Compositions of polylactide (PLA) with polysaccharides ethyl cellulose and chitosan are obtained at different initial ratios of components under conditions of shear deformation in a Brabender mixer. It has been shown that the addition of a given amount of low-molecular poly(ethylene glycol) (PEG) le...
