Shandong Tongchuang Chemical has applied for a patent regarding silicone photoinitiators containing benzophenone derivatives and their preparation methods, which improves the compatibility between these photoinitiators and polymer systems. August 6, 2025, 20:23 · According to information from the Intellectual Property Office, Shandong Tongchuang Chemical Technology Co., Ltd. has filed a patent titled “Silicone Photoinitiators Containing Benzophenone Derivatives and Their Preparation Methods”; the publication number is CN120424343A, and the application was submitted in May 2025. The patent abstract indicates that this invention relates to the field of photoinitiator preparation, specifically to a silicone photoinitiator containing a benzophenone derivative and its preparation method. This photoinitiator consists of 5–10 parts of hydrogenated polysiloxane, 3.38–27.69 parts of benzophenone-initiating units, 60–130 parts of toluene, and 0.0005–0.0006 parts of platinum catalyst. This photoinitiator is prepared by an addition reaction between a benzophenone derivative containing a double bond and a hydrogen-containing polysiloxane. When applied to silicone polymer systems, this photoinitiator improves the compatibility between the photoinitiator and the polymer system, while also reducing the migration rate of residual small-molecule photoinitiators, thereby further enhancing the initiation efficiency of the product. According to Tianyancha, Shandong Tongchuang Chemical Technology Co., Ltd. was established in 2021 and is located in Heze City; it is a company that focuses on the promotion and application of technology in its operations. The registered capital of the enterprise is 70 million RMB. According to Tianyancha’s big data analysis, Shandong Tongchuang Chemical Technology Co., Ltd. has participated in 4 bidding projects and holds 8 patent records; in addition, the company possesses 7 administrative licenses.
