| Abstract: | An intumescent flame retardant poly(2-acyl ethyl(phenyl) phosphinic acyl piperazine) was synthesized from 2-carboxyl ethyl(phenyl) phosphinic acid and piperazine under solvent-free condition.The optimal synthesis conditions were as follows: the molar ratio of 2-carboxyl ethyl(phenyl) phosphinic acid and piperazine was 1∶1 and the reaction was carried out under 150°C for 8 h.The yield was 100.4%.The structure of the obtained product was characterized by IR,NMR and EA,DSC.The flame retardance of the prodect was tested. |
