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).

Novel polyhedral oligomeric silsesquioxane (POSS) resists, which are based on a new photo-crosslinking system via Wolff rearrangement, are developed as ideal replica mold materials for ultraviolet-nanoimprint lithography. These POSS resist materials are synthesized by incorporating diazoketo and hydroxyl groups into
