Document Type and Number:
WIPO Patent Application WO/2019/127989
Kind Code:
A1
Abstract:
Provided are a modified cyanate ester and a preparation method therefor, the preparation method comprising: heating cyanate ester and triethylamine until melted; adding octa-epoxy group cage-type silsesquioxane to the cyanate ester and triethylamine melting system; mixing uniformly, dispersing, and vacuum suctioning to obtain a mixture; casting the mixture in a mould, curing, de-moulding, and heating to obtain modified cyanate ester. The cyanate ester is modified using the octa-epoxy group cage-type silsesquioxane, implementing toughening modification of the cyanate ester whilst maintaining the excellent dielectric properties of the cyanate ester.
