s-Triazine-based functional monomers with thermocrosslinkable propargyl units: Synthesis and conversion to the heat-resistant polymers

s-Triazine-based functional monomers with thermo-polymerizable propargyl-ether units are reported here. Thermopolymerization of the monomers gave the crosslinked networks, showing high low coefficients of thermal expansion (CTE) high glass transition temperatures (Tg). These monomers were also used to improve the properties of a commercial bismaleimide, producing the copolymers with the better thermostability than that the neat bismaleimide.163
