1-benzoxazin-4-one) (BBON) has been proved to be an effective chainextender for poly (ethylene terephthalate) (PET). In order to study the reaction mechanismand kinetics of chain-extending reaction
β-bishydroxyethylene terephthalate (BHET) wasselected as model compound. The NMR data
IR spectra and number average molecularweight (M
n
) of the products obtained from the reaction of BBON and BHET verify thatBBON is a hydroxyl-reactive extender. The mechanism was discussed. Kinetics dataindicate that extending reaction is a second order reaction
and BBON has high reactivity.The activation energy (E
a
) was measured.
