Paragraph 0030; 0031; 0035; 0036; 0040; 0041, (2019/01/06)
The invention provides a superbranched polymer called pentaerythritol tetra((N,N-bis(2-aminoethyl)-3-aminopropionate) with chemical formula being C[CH2OCOCH2CH2N(CH2CH2NH2)2]4. The water-soluble superbranched polymer, with amino groups being terminals and pentaerythritol being a core, can effectively inhibit generation of SiO2 and silicate scales in water. The invention also provides a preparationmethod for the superbranched polymer, comprising: 1) performing primary amino protection on diethylenetriamine; 2) performing an addition reaction with pentaerythritol tetraacrylate; 3) performing hydrolysis for removing amino protective groups to obtain the tetra((N,N-bis(2-aminoethyl)-3-aminopropionate). The method is simple in steps and low in cost.
PEHAM DENDRIMERS FOR USE IN AGRICULTURE
-
Page/Page column 37, (2011/05/11)
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.
