Patent number: 11866537Abstract: The present invention discloses an easy-to-process, opaque and high-impact methyl methacrylate-butadiene-styrene (MBS) polymer for polyvinyl chloride (PVC) and a preparation method thereof, and relates to the technical field of preparation of PVC additives. The easy-to-process, opaque and high-impact MBS for PVC has a core-kernel-shell (three-layer) structure, and includes the following components by mass: 1-20% of core, 70-85% of kernel and 5-20% of shell. The core is a semi-hard, lightly crosslinked copolymer of a styrene (St) monomer and an acrylate monomer. The kernel is a soft, lightly crosslinked butadiene (BD)-St polymer with a low glass transition temperature. The shell is a copolymer of St, butyl acrylate and methyl methacrylate (MMA) with a high glass transition temperature. The present invention solves the problems of low impact strength and poor processing fluidity of the existing MBS for opaque PVC products.Type: GrantFiled: December 14, 2019Date of Patent: January 9, 2024Assignee: SHANDONG DONGLIN NEW MATERIALS CO., LTDInventors: Xiaoquan Zhang, Tonggang Yi, Yongquan Xia, Honggang Zhao, Duo Xu, Boxiao Zou, Wen Liu, Xiaomin Ma

Publication number: 20200405823Abstract: Alcohol intoxication causes serious diseases, whereas current treatments are mostly supportive and unable to remove alcohol efficiently. Upon alcohol consumption, alcohol is sequentially oxidized to acetaldehyde and acetate by the endogenous alcohol dehydrogenase and aldehyde dehydrogenase, respectively. We disclose a hepatocyte-mimicking antidote for alcohol intoxication through the co-delivery of the nanocapsules of alcohol oxidase (AOx), catalase (CAT), and aldehyde dehydrogenase (ALDH) to the liver, where AOx and CAT catalyze the oxidation of alcohol to acetaldehyde, while ALDH catalyzes the oxidation of acetaldehyde to acetate. Administered to alcohol-intoxicated mice, the antidote rapidly accumulates in the liver and enables a significant reduction of the blood alcohol concentration. Moreover, blood acetaldehyde concentration is maintained at an extremely low level, significantly contributing to liver protection.Type: ApplicationFiled: March 29, 2019Publication date: December 31, 2020Applicant: The Regents of the University of CaliforniaInventors: Yunfeng Lu, Cheng Ji, Duo Xu, Hui Han
