【摘要】 对熔融法合成的苯并恶嗪树脂的固化收缩行为及热稳定性能进行了研究。结果表明,苯并恶嗪树脂固化时体积几乎不收缩,甚至略有膨胀,而且具有较高的热稳定性,是一类很有发展前途的新型耐热树脂。更多还原

【Abstract】 The volume shrinkage upon curing and the heat stability of polybenzoxazinc by melting polymezition were investigated. The result showed: Shrinkage of volume in curing reaction of benzoxazine is near- zero. Polybenzoxazine has more excellent heat stability propeties than traditional phenolic resin and is a novel and excellent resin .更多还原
