摘要

正

2’-Bis （4H-3

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

） 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

） was measured.
