a
The concentration of water was based on the total final weight of the adhesive resin.
b
Viscosities were measured with a TA Instruments AR2000 rheometer in the controlled-rate mode at 25 °C with 40 mm diameter and 2 ° cone angle in the shear rate range of 10/s to 100/s, at 10 points per decade. The data are presented as mean values with standard deviations in parentheses.
c
DC was determined by by using a LabRAM ARAMIS Raman spectrometer.
