STUDY ON THE MA-BENZOXAZINE/PHENOLIC-CYANATE RESIN BLENDS

Abstract

Abstract: MA-NCE resin blends based on aldehyde-containing benzoxazine/methylene dianilinebis-benzoxazine resin (MA) and cyanate ester (NCE) were prepared. The gelation time and curing behavior of the blends and thermal mechanical property of the cured products were characterized. Then diisocyanate (MDI) was added into the blend as a polymerization retarder and the influence of MDI was discussed. The results show that, with the increase of cyanate ester content in the blends, Tg increased and modulus decreased; the addition of diisocyanate can effectively prolong the gelation time and improve the processing performance of the blend. Finally, a new high Tg resin used for hot melt prepreg is developed.

Key words: benzoxazine, cyanate, isocyanate, blend
