This invention is directed to a shelf-stable, powder composition adapted to form a high Tg, thermally stable, impact resistant thermoset material. The composition consists essentially of a mixture of an allyl-functional prepolymer component and polymaleimide component. The allyl-functional prepolymer component is the reaction product of an aromatic allyl-functional compound and a modifying compound.
                            本发明涉及一种可在货架上保存的粉末组合物,可形成一种高 Tg、热稳定、抗冲击的热固性材料。该组合物主要由烯丙基官能团预聚物组分和聚马来
酰亚胺组分的混合物组成。烯丙基官能团预聚物成分是芳香族烯丙基官能团化合物和改性化合物的反应产物。
