Application
- Synthesis and Studies on the Effect of Phenyl Side–Chain Content on Refractive Index of Polysiloxane Resin: This study used 1,3-divinyltetramethyldisiloxane as a terminating agent to modify polysiloxane resin properties (Ramli et al., 2015).
- Undecenoic Acid-Based Polydimethylsiloxanes Obtained by Hydrosilylation and Hydrothiolation Reactions: This paper explored the use of 1,3-divinyltetramethyldisiloxane as a blocking agent in the synthesis of polydimethylsiloxanes (Milenin et al., 2020).
- Efficient Improvement in Electrochemical Properties of High-Voltage Li-rich Mn-Based Layered Oxide Cathode by Addition of 1,3-divinyltetramethyldisiloxane: The additive 1,3-divinyltetramethyldisiloxane was used to enhance electrochemical properties of Li-rich layered oxide cathode (Huang et al., 2023).
