As commercial phthalate plasticizers for poly(vinyl chloride), such as DEHP, have been known as environmental hormones, the restriction on their use have been intensified recently. Also, their low molecular weight promotes migration from products when they contact with harsh environment. We estimated hyperbranched polyglycidol derivatives as alternative plasticizers to phthalates. Hyperbrnahced polglycidols with alkyl chains of 2 to 8 were synthesized and PVC films blended with 60 phr of plasticizers were fabricated. Miscibility and glass transition of plasticized PVC were measured by DSC analysis. Mechanical property, thermal stability, transparency and migration resistance were evaluated by tensile test, TGA, UV/Vis spectroscopy and leaching test, respectively. In addition, general toxicity of plasticizer was executed via oral rat toxicity. From the results, we confirmed hyperbranched polyglycidol derivatives are promising alternative plasticizers.
