POLYMER PLASTICIZING AGENTS THAT PRODUCE POLYMERS THAT DO NOT RELEASE ENDOCRINE DISRUPTING COMPOUNDS

摘要

Disclosed are novel phthalate compounds and a simple and economical route to covalently attach a phthalate ester mimic to PVC is described, allowing plasticization of PVC without the danger of Endocrine Disruption Chemicals leaching from the polymer matrix. An azide-alkyne Husigen cycloaddition (in the absences of copper catalyst) using dialkyl acetylenedicarboxylates allows this cycloaddition to occur under very mild thermal conditions.
