MUMBAI, India, April 10 -- Intellectual Property India has published a patent application (202411073568 A) filed by Council Of Scientific And Industrial Research, New Delhi, on Sept. 27, 2024, for 'squaraine dyes based photocatalysts for preparation of polymers.'
Inventor(s) include Ashootosh Vasant Ambade; Jayaraj Nithyanandhan; Indrajeet Sadashiv Nawghare; and Anil Mahadev Patil.
The application for the patent was published on April 10, under issue no. 15/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to photocatalysts of formula I for controlled radical polymerization including photoinduced electron transfer-reversible addition-fragmentation chain transfer PET-RAFT polymerization. The present invention also discloses a process of preparation of polymers including copolymers, block copolymers, homopolymers and/or related polymers/copolymers where two or more monomers are reacted in presence of said a squaraine dye based photocatalyst of formula I, chain transfer agent (CTA), and light source, and optionally in presence of a catalyst activator in both batch and flow modes. The process of the present invention significantly reduces the induction period in the photocatalyzed controlled radical polymerization and also affords shorter reaction time of photocatalyzed controlled radical polymerization."
