Abstract
Abstract Novel polyfunctional maleimides as well as novel compositions based on mono- and polyfunctional maleimides are provided. Also provided are heat resistance resin compositions and curable compositions incorporating the same. The monofunctional maleimide is N-(2,3-dimethylphenyl)maleimide, and the polyfunctional maleimides are bis- and higher functional variations thereof.
