文摘

(2-Ethylhexyl) phthalate esters are synthesized with ester or ether alkyne linkages. These derivatized alkyne phthalates react with a simple secondary azide model. Phthalates are attached to azidized PVC by thermal or Cu catalyzed cycloaddition. The rotationally free ether is a better internal plasticizer by Tg than the ester.
