Abstract
The invention relates to the use of dicyanamide-containing ionic liquids which decrease the cure temperature of cyanate esters to form unique thermoset polymers having a triazine network. These thermoset polymers having the triazine network have an ionic character allowing for use in varied applications. The thermoset polymers described herein are useful in high temperature performance composites, and their high Tg makes them useful as a substitute for epoxies in the microelectronics industry. The thermoset polymers have good fracture toughness, excellent substrate adhesion, low shrinkage, and low moisture uptake.
Claims17
A curable composition for preparing a thermoset polymer having a triazine network, said curable composition comprising:
- (a) a cyanate ester monomer;
- and
- (b) at least one ionic liquid comprising a dicyanamide anion.
A method of preparing a thermoset polymer having a triazine network comprising combining, in any order, the following:
- (a) a cyanate ester monomer;
- and
- (b) at least one ionic liquid comprising a dicyanamide anion, to form a mixture, and heating the mixture to a temperature sufficient to cause a curing reaction to thereby form the thermoset polymer having a triazine network.
