MUMBAI, India, Sept. 22 -- Intellectual Property India has published a patent application (202647109073 A) filed by Basell Poliolefine Italia S. R. L. on September 11, 2026, for Pretreatment Of Polyolefin Waste To Improve Depolymerization.
Inventors include White, Daniel F.; Nagy, Sandor; Smith, Christopher D.; and Menichelli, Francesco.
The application for the patent was published on September 18, 2026, under issue no. 38/2026.
Abstract: A method for treating a polymer recyclate to produce an improved depolymerization feed is described. The method comprises providing a polymer recyclate comprising a polyolefin component and a polar polymer component, wherein the polar polymer component comprises heteroatom bonds. The polymer recyclate is subjected to reaction conditions sufficient to degrade at least a portion of heteroatom bonds to produce a degraded polar polymer component and a waste gas comprising hetero- containing compounds. An improved depolymerization feed, comprising the polyolefin component and the degraded polar polymer component, is recovered. Also, disclosed is a depolymerization process comprising a step of pretreating a polymer recyclate according to the disclosed method.
