Title:
REACTIVE TYPE PHOSPHATE AND PREPARATION PROCESS
Document Type and Number:
WIPO Patent Application WO/2021/237695
Kind Code:
A1
Abstract:
Provided herein are phosphorus-based flame retardant compounds that provide both good electrical characteristics and good heat resistance characteristics when incorporated into PCB compositions. In particular, provided herein are new organophosphorus-based polymers that contain C=C double bonds, which allows them react with other components (for example, C=C bond capped polyphenyl ether, unsaturated hydrocarbon resin, bismaleic imide, etc. ) to form a crosslinked network.
