Hydrolyzable Polyureas Bearing Hindered Urea Bonds
Hydrolyzable polymers are widely used materials that have found numerous applications in biomedical, agricultural, plastic, and packaging industrials. They usually contain ester and other hydrolyzable bonds, such as anhydride, acetal, ketal, or imine, in their backbone structures. Here, we report the first design of hydrolyzable polyureas bearing dynamic hindered urea bonds (HUBs) that can reve...

متن کاملSynthesis and Anticoagulant Activity of Polyureas Containing Sulfated Carbohydrates
Polyurea-based synthetic glycopolymers containing sulfated glucose, mannose, glucosamine, or lactose as pendant groups have been synthesized by step-growth polymerization of hexamethylene diisocyanate and corresponding secondary diamines. The obtained polymers were characterized by gel permeation chromatography, nuclear magnetic resonance spectroscopy, and Fourier transform infrared spectroscop...
متن کاملEnzymatic Synthesis of Biobased Polyesters and Polyamides
Nowadays, “green” is a hot topic almost everywhere, from retailers to universities to industries; and achieving a green status has become a universal aim. However, polymers are commonly considered not to be “green”, being associated with massive energy consumption and severe pollution problems (for example, the “Plastic Soup”) as a public stereotype. To achieve green polymers, three elements sh...
متن کاملSYNTHESIS OF SELENAZOL0[3,2-b] [ 1,2,4] TRIAZINE AND SELENAZOLO [2,3-C] [I ,2,4] TRIAZINE
6-Methyl- 1,2,4-triazine-3-(2H)-selenone-5(4H)-one(l) reacts in the presence of base with phenacyl bromide to give a mixture of compounds (2) and (3). This mixture is dehydrated in the presence of H,SO, to give 3-phenyl-6 methyl-7H-selenazolo[3,2-b] [I ,2,4] triazin-7-one (6). For careful structure assignment of (6) its regioisomer 3-methyl-6-phenyl-4H-selenazolo [2,3-c] [ 1,2,4] triazin-4-one...
