摘要

Copolymers of 1,1,1,3,3,3-hexafluoroisopropyl methacrylate (HFIPM) and tert-butyl methacrylate (TBM) were prepared by conventional radical copolymerization as a novel binders for pressure-sensitive paints (PSP). The monomer reactivity ratios r(HFIPM) and r(TBM) were determined as 0.45 and 0.67, respectively. The glass transition temperature of the copolymers increased from 77 to 126 degrees C with increasing mole fraction of TBM units in the copolymer. The PSP were formed by combining the resulting copolymers and 5,10,15,20-tetrakis(pentafluorophenyl)porphinato platinum(II). The pressure and temperature sensitivities of the PSPs were measured at air pressures ranging from 5 to 120 kPa and at temperatures ranging from 0 to 60 degrees C. Modified Stern-Volmer plots indicated slight increases in the pressure sensitivity, but significant decrease in the temperature sensitivity as the mole fraction of HFIPM units increased in the copolymer. Applying a theoretical model to our calibration data, we inferred that luminescence quenching is primarily responsible for increasing the temperature sensitivity in the resulting copolymers.
