A novel method for preparing a thermosetting imide resin composition which consists of chemically reacting a liquid mixture of a vinylidene -terminated polybutadiene/ acrylonitrile (VTBN) and a co-reactant comprising
a. at least one N,N'-bisimide of an unsaturated carboxylic acid of general formula I
wherein B represents a divalent radical containing a carbon-carbon double bond and A represents a divalent radical having at least two carbon atoms, or
b. the amide resin reaction product of at least one N,N'-bisimide of general formula I and at least one primary organic diamine or organic hydrazide, or
c. the imide resin reaction product of at least one N,N'-bisimide of general formula I, at least one monoimide, and at least one organic hydrazide,
to yield a thermosetting imide resin composition containing copolymerised VTBN and co-reactant. A resin composition prepared by this method may be cured at a temperature between 100°C and 350°C to yield a fully cross-linked polyimide matrix containing a dispersion of phase-separated solid particles of copolymerised VTBN and co-reactant.
一种制备热固性酰亚胺树脂组合物的新方法,包括使一种以乙烯基为端基的聚丁二烯/丙烯腈(VTBN)和一种共反应物的液体混合物发生化学反应,该共反应物包括
a. 至少一种通式 I 的不饱和羧酸的 N,N'-二亚胺
其中 B 代表含有碳碳双键的二价基,A 代表至少含有两个碳原子的二价基,或
b. 至少一种通式 I 的 N,N'-二亚胺与至少一种伯氨基有机二胺或有机酰肼的酰胺 树脂反应产物,或
c. 至少一种通式 I 的 N,N'-二亚胺、至少一种单亚胺和至少一种有机酰肼的亚胺树脂反应产物、
生成含有共聚 VTBN 和共反应物的热固性亚胺树脂组合物。用这种方法制备的树脂组合物可在 100°C 至 350°C 的温度下固化,以产生完全交联的聚酰亚胺基体,其中含有共聚 VTBN 和共反应物的相分离固体颗粒的分散体。
