THE RHEOLOGICAL BEHAVIOR DURING CURING OF 4,4’-DIAMINODIPHENYL SULPHONE(DDS)-CURED TETRA-GLYCIDYL 4,4’-DIAMINODIPHENYL METHANE EPOXY (TGDDM)

Considerable works on curing reaction,network steasture and physical properties of TGDDM/DDS resin systerm have been published,yet there is less publications on rhcological behavior during curing reaction.In the present paper a constitutive equation the viscosity and time as well as curing temperacure have been proposed.Experimntal results conformed well to the equationg prediction.
