Highly refractive and transparent polyamides containing thiadiazole units have been developed.These polymers were prepared by a polycondensation reaction of 4,4
The efficient and one-pot synthesis of 4-substituted-1,2,4-triazolidin-3,5-dione derivatives(4-substituted urazoles) via combination of triphosgene, substituted
Rubbers have been well accepted for modifying brittle epoxies but rubber modified epoxies usually posses lowered tensile strength though enhanced ductility and
