Reactive plasticizers and internal plasticization

Some examples of reactive plasticizers,internal plasticization, and polymer modification are given to show other possibilities of plasticization, which are outside the scope of this monograph. 

Reactive plasticizers give three major advantages in formulated product applications  

In polyimide used for high temperature applieations a plasticizer having very unusual structure is used  

At an elevated temperature, four membered ring undergoes scission and crosslinks polymer. 

Unsaturated trimethylopropane trimethylaciylate is a reactive plasticizer of PVC. Its reaction is initiated by addition of peroxide. Because of crosslinking, PVC material has increased resistance to creep at elevated temperatures.
