Colorimetry studies were used to determine synergetic effects between mono, di, tri, or tetra esters of pentaerythritol (PE) with crude fatty acid (C-14-C24 saturated fatty acids mixture) (FHA) obtained from hydrogenated fish oil and zinc stearate/calcium stearate synergetic soap, on the thermal stabilization of poly(vinyl chloride) (PVC). The image processing evaluation of dispersion degree of PE-FHA esters into PVC showed that dispersion degree of the ester was improved with increasing esterification degree. The compatibility of PE-FHA esters, prepared with fatty acid mixtuer, was superior to that of PE-stearic acid esters. Synergisms of PE-FHA esters except tri and tetra esters with synergetic metal soap exhibited a marked effect, showing a efficiency similar to the case of compounding PE-stearic acid esters. The noticeble effect of the diester is due to the unesterificated two hydroxy groups which exhibit the masking effect and good compatibility with PVC. These results give helpful suggestions concerning the practical development of co-stabilizer for PVC.
