  • Pentaerythritol core, phosphonic acid terminated dendrimer and its preparation method
    Patent number: 9403707
    Abstract: A pentaerythritol core, phosphonic acid terminated dendrimer, its preparation method and application are provided. A preparation method of the pentaerythritol core, phosphonic acid terminated dendrimer (PETA-ADA-12PO3H2) comprises steps of processing Michael addition reaction on pentaerythritol tetraacrylate (C(CH2OCOCH2=CH2)4) and alkylidene diamine (NH2CH2(CH2)nNH2), wherein n is an integer from 1 to 5, so as to obtain pentaerythritol core, amino group terminated dendrimer, and modifying the amino group by methylene phosphonic acid to obtain the PETA-ADA-12PO3H2 having a chemical formula of C[CH2OCOCH2CH2N(CH2PO3H2)CH2(CH2)nN(CH2PO3H2)2]4, wherein n is an integer from 1 to 5.
