______________ is used as a blending agent with epoxy resin to increase its glass transition temperature, modulus and tensile strength of epoxy resin.

______________ is used as a blending agent with epoxy resin to increase its glass transition temperature, modulus and tensile strength of epoxy resin. Correct Answer Polyether sulfone

Polyether sulfone is used as a blending agent. During polymerization the epoxy material gets toughen and thus decreases the glass transition temperature, modulus and tensile strength. Diethylene triamine (DETA) and Diamino diphenyl sulfone (DDS) are used as the curing agents. Diglycidyl ether of bisphenol A (DGEBA) is used as a starting material of epoxy.
