MUMBAI, India, April 17 -- Intellectual Property India has published a patent application (202531097612 A) filed by Narula Institute Of Technology, Kolkata, West Bengal, on Oct. 9, 2025, for 'pvc-polymethyl methacrylate full ipn and its mechanical property modification.'
Inventor(s) include Dr. Rupa Bhattacharyya; Dr. Sarbani Ganguly; and Dr. Sumit Nandi.
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 study under consideration aims at generating a full IPN with PVC and PMMA with the composition ratio of 75:25 of PVC:PMMA. The product so formed exhibited enhanced mechanical behavior in terms of ultimate tensile strength, modulus and toughness from unmodified PVC compound. The thermal properties were also significantly improved as its degradation temperature was raised from 2430C to 3010C and 2720C to 3290C. It was observed that the introduction of PMMA into the PVC matrix and corresponding IPN formation produced a directing influence to enhance the mechanical and thermal properties significantly over that of unmodified base PVC compound. So, the product generated carries immense potential of commercialization and PVC full IPN product with better strength and durability can be synthesized to enrich the market of commodity plastics."
