The pNIPAM FT-IR spectra present the stretching vibration band of N-H around of 3300 [cm.sup.-1] at at 1642 [cm.sup.-1], and 1526 [cm.sup.-1], with slight shift to lower wavelength for the spectra of pNIPAM/PAS sIPN. The bands between 2835 [cm.sup.-1] and 3000 [cm.sup.-1] are associated with the C-H stretching vibrations of the methyl groups of N-isopropyl groups.
In the FT-IR spectra of the sIPN structure, the absorption band registered at 1739 [cm.sup.-1] is assigned to the carboxyl group from the PAS copartner agent, confirming the incorporation of the PAS into the pNIPAM network as well the successful crosslinking reaction of the thermo-sensitive polymer.
To confirm the data resulted from FTIR spectra concerning sIPN formation, the tested samples were evaluated through the NIR-CI method as a non-destructive way of characterization.

Besides SIPN, simply mixing of SF with one or more polymers is also considered as an effective mean that was sought for versatile SF-based gels.
We have recently investigated the introduction of small quantities (5% to 15% by weight) of several crosslinked thermoset networks (epoxy, vinyl ester, and several isocyanate systems) into thermoplastic PVC to develop PVC/thermoset SIPN blends (5-9).
As crosslinking occurs to generate the SIPN, the entropy of mixing decreases.
This network is now fixed within amorphous regions of the PVC matrix (interdomain mixing in what has become a mixed thermoset/PVC SIPN domain).
Five to seven SIPN specimens were tested and the average value was used.
Three 1.8 to 2.2 g samples of each SIPN blend were continuously extracted with THF at 45[degrees]C for 48 h.
These combined effects are called the "dilution effect." The longer gel time and delay of phase separation may permit more complete SIPN formation per thermoset increment.
