Abstract
Official abstract text for this publication.
The present invention relates to a benzoxazine intermediate and a preparation method thereof. The structural formula of the benzoxazine intermediate is shown by formula (1), R 1 in formula represents O, C═O, S, SO 2 , alicyclic hydrocarbon with 3 to 30 carbon atoms and derivatives thereof, aliphatic hydrocarbon with 1 to 20 carbon atoms and derivatives thereof, or unsaturated aliphatic hydrocarbon with 2 to 20 carbon atoms and derivatives thereof; R 2 is alicyclic hydrocarbon with 3 to 20 carbon atoms and derivatives thereof, aliphatic hydrocarbon with 1 to 20 carbon atoms and derivatives thereof, or unsaturated aliphatic hydrocarbon with 2 to 20 carbon atoms and derivatives thereof. The benzoxazine intermediate of the present invention contains a naphthalene ring structure segment, has desirable heat resistance performance and flame retarding performance, and can be widely applied in composite materials.
