Abstract

The creation of environmentally friendly polymeric materials able to decompose at the end of their service life under the environment, in particular, by replacing the original nonrenewable components with natural ones, is a promising way to decrease the impact of polymer wastes on the environment.

The article examines the effect of natural components (castor and palm vegetable oils, xanthan exopolysaccharide), the mass fraction of which amounts to 70 wt.% on the structure, thermal and viscoelastic properties of water-based polyurethanes. The structure - properties relationship was confirmed by wide and small-angle X-rays scattering, DMA, TGA and DSC analysis. The presence of components of natural origin have been shown to affect the structure, viscoelastic behavior and thermal properties of studied polyurethanes. The data obtained made it possible to conclude the possibility of obtaining stable polyurethanes with an adjustable set of properties depending on the amount and nature of the renewable raw materials.

摘要

创造能够在其使用寿命结束时在环境下分解的环保聚合物材料，特别是通过用天然成分代替原始不可再生成分，是减少聚合物废物对环境影响的一种有前途的方法。

本文研究了天然成分（蓖麻油和棕榈植物油、黄原胶胞外多糖）对水性聚氨酯的结构、热和粘弹性的影响，其质量分数达到 70 wt.%。通过广角和小角X射线散射、DMA、TGA和DSC分析证实了结构-性质关系。已证明天然成分的存在会影响所研究聚氨酯的结构、粘弹性行为和热性能。所获得的数据使得我们有可能根据可再生原材料的数量和性质得出具有一组可调整性能的稳定聚氨酯的可能性。
