- Trimethylolpropane tris((N,N-bis(2-aminoethyl))-3-aminopropionate) and preparation method and application thereof
-
The present invention provides a hyperbranched polymer named trimethylolpropane tris((N,N-bis(2-aminoethyl))-3-aminopropionate). The chemical formula of the hyperbranched polymer is CH3CH2C[CH2OCOCH2CH2N(CH2CH2NH2)2]3. The hyperbranched polymer is a water-soluble hyperbranched polymer of an amino-terminated trimethylolpropane core and can effectively inhibit the formation of silicon dioxide scaleand silicate scale in water. The invention also provides a preparation method of the hyperbranched polymer. The preparation method comprises the following steps of: firstly, carrying out primary aminoprotection on diethylenetriamine, then carrying out addition reaction with trimethylolpropane triacrylate, and finally hydrolyzing to remove amino-protecting groups to obtain the trimethylolpropane tris((N,N-bis(2-aminoethyl))-3-aminopropionate). The preparation method provided by the invention has simple steps and low cost.

- PEHAM DENDRIMERS FOR USE IN AGRICULTURE
-
Specific PEHAM dendrimers are used in a formulation with an active agent for agricultural purposes, particularly for increasing the efficacy of the active agent in various ways, such as by improving solubility of the active agent in the formulation, by improving adhesion and penetration of the active agent to plant surfaces, by improving the water- fastness of the active agent to the plant or seed, by providing protection of the active agent from UV damage, by increasing soil penetration of the active agent to reach the plant roots or under soil parts, or by reducing soil adhesion of the active agent to reach the plant roots or under soil parts, or reducing enzymatic degradation of the active agent by the plant or seed or microorganisms in the soil.

- DENDRITIC POLYMERS WITH ENHANCED AMPLIFICATION AND INTERIOR FUNCTIONALITY
-
Dendritic polymers with enhanced amplification and interior functionality are disclosed. These dendritic polymers are made by use of fast, reactive ring-opening chemistry (or other fast reactions) combined with the use of branch cell reagents in a controlled way to rapidly and precisely build dendritic structures, generation by generation, with cleaner chemistry, often single products, lower excesses of reagents, lower levels of dilution, higher capacity method, more easily scaled to commercial dimensions, new ranges of materials, and lower cost. The dendritic compositions prepared have novel internal functionality, greater stability (e.g., thermal stability and less or no reverse Michael's reaction), and reach encapsulation surface densities at lower generations. Unexpectedly, these reactions of polyfunctional branch cell reagents with polyfunctional cores do not create cross-linked materials. Such dendritic polymers are useful as demulsifiers for oil/water emulsions, wet strength agents in the manufacture of paper, proton scavengers, polymers, nanoscale monomers, calibration standards for electron microscopy, making size selective membranes, and agents for modifying viscosity in aqueous formulations such as paint. When these dendritic polymers have a carried material associated with their surface and/or interior, then these dendritic polymers have additional properties for carrying materials due to the unique characteristics of the dendritic polymer, such as for drug delivery, transfection, and diagnostics.
