New Control Over Silicone Synthesis using SiH Chemistry: The Piers–Rubinsztajn Reaction
10.1002/chem.201800123 2018-03-30 There is a strong imperative to synthesize polymers with highly controlled structures and narrow property ranges. Silicone polymers do not lend themselves to this paradigm because acids or bases lead to siloxane equilibration and loss of structure. By contras... |
