Highly Flexible PVC Materials without Plasticizer Migration As Obtained by Efficient One-Pot Procedure Using Trichlorotriazine Chemistry

A synthetic approach for the preparation and linkage of functionalized plasticizer molecules to PVC is described. The synthesis of this four-step procedure is economically and ecologically viable because it is based on trichlorotriazine as inexpensive starting material; the reactions can be carried out one-pot with quantitative yields and without need of final purification of the products. The approach is furthermore highly versatile and allows for the preparation of a large number of different plasticizers with properties that may be adjusted to a broad range of applications from highly flexible to semirigid.The authors gratefully acknowledge support from Grant MAT 2013-42957-R.
