Bis-p-toluenesulfonates of Diamino-diesters Based on Cyclic Diols – New Key Monomers for Obtaining High-modulus Pseudoproteins

Environmental pollution caused by placing polymer waste into the environment without proper recycling is one of the most acute problems existing nowadays in terms of environmental stability. This problem has been exacerbated during the Covid-19 period. Covid-19 threatened not only human health but it negatively affected environmental stability. (According to credible statistical data every day about 8 million polymer waste is released into oceans [1], [2]). Recycling polymer material requires significant financial contribution along with human resources and time. According to the fact that demands on biodegradable materials have increased because after their exploitation period, they will not pollute the environment. This research is about synthesizing inflexible structured monomers and also the synthesis of new polymers based on the above-mentioned monomers is discussed. In this research synthesis of six new monomers (Tozyl diaminodiesters) is provided along with some polymer polyester urea synthesis techniques. It should be noted that these kinds of polymers might be used in the field of medicine but after taking into consideration their mechanical properties they might be used in specific parts of the engineering field as well.
