Poly(butylene terephthalate) (PBT) was used as a semicrystalline modifier of epoxy-aromatic diamine formulations. The epoxy monomer was based on diglycidylether of bisphenol A (DGEBA) and the diamines were either 4,4 -methylenebis [3-chloro 2,6-diethylaniline] (MCDEA) or 4,4 -diaminodiphenyl-sulfone (DDS). PBT was more miscible in DGEBA-MCDEA than in DGEBA-DDS formulations, as revealed by the...
Poly(butylene terephthalate) (PBT) was used as a semicrystalline modifier of epoxy-aromatic diamine formulations in concentrations ranging from about 3 wt% to 8 wt%. The epoxy monomer was based on diglycidylether of bisphenol A (DGEBA) and the diamines were either 4,4 -methylenebis [3-chloro 2,6-diethylaniline] (MCDEA) and 4,4 -diaminodiphenylsulfone (DDS). Using conversion-temperature transformation...
