Title:
MODIFIED BISMALEIMIDE PREPOLYMER, PREPARATION METHOD THEREFOR, AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/134589
Kind Code:
A1
Abstract:
The present invention relates to a modified bismaleimide prepolymer, a preparation method therefor, and an application thereof. The present invention uses a suitable type of allyl compound to perform modification on a bismaleimide resin, a modified bismaleimide prepolymer is obtained, and a laminate board prepared using said prepolymer as a raw material has high peel strength. Moreover, the inventors have further discovered that the modified bismaleimide prepolymer has good miscibility with another resin, can further be dissolved in a common solvent, and is easy to cure. Also, the laminate board prepared using the modified bismaleimide prepolymer as a raw material has very good heat resistance and toughness.
