| Abstract: | A silicon‐containing benzoxazine BATMS‐Bz (1,3‐bis(3‐aminopropyl)tetramethyldisiloxane‐benzoxazine) was used for polybenzoxazine modification by means of formation of benzoxazine copolymers with 3,4‐dihydro‐3‐phenyl‐2H‐1,3‐benzoxazine (Ph‐Bz) and 3‐furfuryl‐3,4‐dihydro‐2H‐1,3‐benzoxazine (F‐Bz), respectively. Ph‐Bz/BATMS‐Bz copolymers showed a positive deviation due the presence of intermolecular hydrogen bonding. However, this effect was not observed with F‐Bz/BATMS‐Bz copolymers. Meanwhile, BATMS‐Bz incorporation exhibited significant effect on toughening polybenzoxazines. It is therefore demonstrated that BATMS‐Bz is a high performance modifier to simultaneously enhance the Tg and toughness of polybenzoxazines. © 2006 Wiley Periodicals, Inc.
