Reactive Functionally Terminated Siloxane Oligomers

The main factors determining the reactivity of these siloxane oligomers towards other reactants are the type and nature of the terminal functional groups. Due to the fundamental differences in their structures, chemical reactivities and overall properties,

General structure of the (Si—X) terminated siloxane oligomers and a list of important reactive functional end groups (X) are given in Table 2. 

As expected, the terminal functional groups mainly determine the reactivity of these siloxane oligomers towards other reactants. The variations in the backbone composition have critical effects on the glass transition temperature, solubility parameter, thermal stability and surface behavior of the resulting oligomers(12,13).
