文摘A new class of crosslinking polyphosphates were synthesized characterizedby IR 1HNMR, 31PNMR spectroscopy as well as elemental analysis. In vitrodegradation of the polyphosphates obtained and the release of antineoplastic drugMethotrexate (MTX) and contraceptive Levonorgestrel (LNG ) by nsing thesepolymers as matrix were studied. Zero order release rate was rkserved in the case ofLNG release.
