Application of complex esters in poly(vinyl chloride)plastisols and plasticats

摘要

Purpose-To evaluate the efficiency of complex esters as plasticizers in polyvinyl chloride plastisols and plasticates.Design/methodology/approach-Several poly(vinyl chloride)plastisols and plasticates were prepared with standard phthalate plasticizers and complex esters and were characterised using standard and laboratory methods.Findings-The use of mixtures of three new CE with standard phthalate plasticizers increased the physical,mechanical and electric characteristics of the resulting PVCPs and PVCPI.Research limitations/implications-The use of three new CE,obtained by esterification of dicarboxylic acids(adipic,sebacic,pelargonic),polyethylene glycol)and i-octanole,as plasticizers of poly(vinyl chloride)plastisols and plasticates was investigated.The use of CE based on other organic acids could be explored.Practical implications-The results confirmed the efficiency of plasticization of PVC by CE.Such a finding has significant industrial implication.Originality/value-Several findings are original and are of importance to relevant industry.The new CE with high molecular weights were effective plasticizers of PVC.The efficiency of the plasticizers depended on their chemical structure.The molecular weight of the CE had no influence on the compatibility of plasticizers and other components of the PVC plastisols and plasticates.
