Solutions of the cyclic boric acid ester, tri-isopropanolamine borate, in benzene have been studied by dipole moment measurements at 25 and 50�C. The molecule has a dipole moment of 6.69 D, and the concentration dependence of the polarization indicates association of the solute, with end-to-end association predominating.

This paper studies the influence of Double (L- diethyl tartrate) boric acid ester (compatibilizer B) on the compatibility between PPO and PA66. Through the mechanical properties, Molau experiment, scanning electron microscope and tem analysis test method, it is proved that Double (L- diethyl tartrate) boric acid ester can be used as a new reactive compatibilizer in PPO/PA66 plastic alloy.

The hydrolysis of tris(organyloxy)boranes (boric acid esters) in organic solvents in the presence of KOH leading to potassium polyborates (free from water of crystallization) is studied as to the influences of (a) the reaction medium (ethanol or ligroine/ethanol), (b) the concentration of water, (c) the organyl group of the boric acid ester (methyl, isopropyl, or phenyl), (d) the time of stay of the precipitated insoluble polyborates under the mother liquor (15 to 61850 s), and (e) the temperature during precipitation and the time of stay (—18 to + 60°C).In the first stage of the reaction, during precipitation time, ester hydrolysis is followed by condensation, while aggregation and desorption processes occur between the time of precipitation and filtration.
