改性氰酸酯树脂及其制备方法
摘要：
本发明提供了一种改性氰酸酯树脂，为双酚A二氰酸酯和含有聚芳醚酮的环氧树脂共聚形成的共聚物，其中，所述双酚A二氰酸酯与含有聚芳醚酮的环氧树脂的质量比为100∶1～200，所述含有聚芳醚酮的环氧树脂具有式(I)、式(II)、式(III)或式(IV)所示的结构。本发明还提供了一种上述技术方案所述的改性氰酸酯树脂的制备方法。本发明在氰酸酯树脂中引入含有聚芳醚酮的环氧树脂，与双酚A二氰酸酯共聚后得到的改性氰酸酯树脂的韧性有所提高。实验表明，与纯双酚A二氰酸酯形成的树脂相比，本发明提供的改性氰酸酯树脂的断裂伸长率可达4.7％。
摘要（英）：

The invention provides a modified cyanate resin, which is a copolymer formed by copolymerization of biscyanatophenylpropane and epoxy resin having polyaryletherketone, wherein the mass ratio of the biscyanatophenylpropane and the epoxy resin having polyaryletherketone is 100:(1-20); and the epoxy resin having polyaryletherketone has a structure shown by a formula (I), formula (II), formula (III) or formula (IV). The invention also provides the preparation method of the modified cyanate resin which is provided according to the technical scheme. In the invention, the epoxy resin having polyaryletherketone is introduced into the cyanate resin, so the toughness of the modified cyanate resin formed by copolymerization with biscyanatophenylpropane is improved. Experiments show that the elongation at break of the modified cyanate resin provided by the invention reaches 4.7 percent which is higher than that of resin formed by pure biscyanatophenylpropane.
