dcterms:description
To prepare polyurethaner materials with improved recycling properties by modifing with starch or cellulose derivatives. capability, new fexible biodegradable polyurethane foams, in which non-degradable polyether polyol was partly substituted by the bio-polyols based on cellulose or starch derivatives were synthesized. The incorporation of bio-polyols into the foams structures as well as their influence on the foam thermal stability was assessed by Fourier-transformed infrared spectroscopy and thermogravimetric analysis analyses. The ecotoxicological aspects of the newly synthesized foams were investigated by extracting the samples using freshwater as a solvent followed by applying the microbiotest screening toxkit under trade name Thamnotoxkit F(TM) with larvae of freshwater shrimps Thamnocephalus platyurus.
