Inventor(s) include Kumar, Suresh; Gupta, Rakesh Kumar; Agnihotri, Amit; Mishra, Raghwesh; Misra, Manoj Kumar; Barua, Sanjay; and Dwivedi, Mayank.
The application for the patent was published on April 17, under issue no. 16/2026.
According to the abstract released by the Intellectual Property India: "The present disclosure relates to a process for preparation of polymetallocarbosilane (m-PCS) from a polycarbosilane and an organometallic compound. Particularly, the present disclosure relates to a process for preparation of polyzirconocarbosilane and polytitanocarbosilane from a polycarbosilane, prepared by reacting Polydimethylsilane (PDMS), liquified low molecular weight Polycarbosilane (LPCS) having a number average molecular weight (Mn) between 200-800 g/mole, and Polyborodiphenylsiloxane (PBDPSO) in a weight ratio in the range of 100:5:0.05 to 100:35:0.6, and an organometallic compound comprising Zirconium, Titanium or mixtures thereof. The Polymetallocarbosilane (m-PCS) prepared according to this disclosure is suitable for spinning ultra-high temperature ceramic fibers as fine as 10 to 20 microns diameters and as long as 10 km to 100 km."
