METHOD OF OBTAINING ABA BLOCK COPOLYMERS, OBTAINABLE PRODUCTS AND USES THEREOF

Synthesis of ABA block copolymers (PVC-b-PBA-b-PVC) from PBA macroinitiators using the SET-DTLRP technique, with the introduction of a temperature step. This introduction of a temperature step is important so that the synthetized block copolymer presents mechanical properties identical to those of p...

More Information
Summary:Synthesis of ABA block copolymers (PVC-b-PBA-b-PVC) from PBA macroinitiators using the SET-DTLRP technique, with the introduction of a temperature step. This introduction of a temperature step is important so that the synthetized block copolymer presents mechanical properties identical to those of plasticised PVC (commercial).The present invention further describes a flexible ABA block copolymer (PVC-b-PBA-b-PVC) and the use thereof in the manufacture of different items.
