In this study, epoxy‐networked polymeric materials containing tributyl (ethyl) phosphonium diethyl phosphate (CYPHOS®IL169) and trihexyl (tetradecyl) phosphonium bis 2,4,4‐(trimethyl pentyl)‐phosphinate (CYPHOS®IL104) were developed from a mixture of epoxy prepolymer (DGEBA) and different amounts of ionic liquids (10–20–30 phr). Then, the effect of the chemical nature of ionic liquids on the final...
The present paper describes for the first time the use of ionic liquid based on trihexyl(tetradecyl)phosphonium bis(2,4,4-trimethylpentyl)phosphinate (IL104), as catalytic curing agent for bisphenol A – based epoxy prepolymer (DGEBA). The curing process was investigated by DSC, rheometry and FTIR analysis, indicating an increasing on the curing rate as the amount of IL in the system increased. The...
