ABSTRACT:
Various phenol-free phosphites for use in PVC as an alternative to the conventional phenol-containing products phenyl diisodecyl phosphite and diphenyl isodecyl phosphite were tested. These phosphites utilize para-cumyl phenol-based derivatives in order to provide a phenol free derivative of the above mentioned conventional phosphites.
