A Brief Introduction to the Polyurethanes According to the Principles of Green Chemistry

Polyurethanes are most often called “green” when they contain natural, renewable additives in their network or chemical structure, such as mono- and polysaccharides, oils (mainly vegetable oils), polyphenols (e.g., lignins, tannins), various compounds derived from agro-waste white biotechnology (Principle 7). This usually results these polyurethanes obtained less hazardous substrates 4). Appropriate modification of makes them susceptible to degradation, the use appropriate processes allows for recycling 10). However, this fulfilment other principles also predisposes be green. As production polymer materials, synthesis is carried out with catalysts (such biocatalysts) 9) full control course reaction 11), which maximization atomic economy 2) an increase energy efficiency 6) while minimizing risk waste 1). Moreover, traditional can replaced toxic ones non-isocyanate polyurethanes), which, at same time, leads a non-toxic product 3, Principle 5). In general, there no need blocking provide intermediates 8). Reasonable storage substrates, transport, guarantee safety prevention uncontrolled reactions 12). publication summary achievements scientists technologists who constantly working create ideal that do not pollute environment, consistent sustainable economy.
