The role of the ratio (PEG:PPG) of a triblock copolymer (PPG‐b‐PEG‐b‐PPG) in the cure kinetics, miscibility and thermal and mechanical properties in an epoxy matrix

The aim of this study was to evaluate the role of different poly(ethylene glycol):poly(propylene glycol) (PEG:PPG) molar ratios in a triblock copolymer in the cure kinetics, miscibility and thermal and mechanical properties in an epoxy matrix. The poly(propylene glycol)‐ block ‐poly(ethylene glycol)‐ block ‐poly(propylene glycol) (PPG‐ b ‐PEG‐ b ‐PPG) triblock copolymers used had two different molecular masses: 3300 and 2000 g mol −1 . The mass...
