Latest Patents

**Polypropylene article and method of preparing polypropylene article.** This invention describes a thermoformed polypropylene article, or a sheet used to make one, combining a layer of substantially syndiotactic polypropylene with a thin outer layer of substantially isotactic polypropylene. The isotactic layer improves processability, while the predominantly syndiotactic composition can provide greater transparency and impact strength than articles made entirely from isotactic polypropylene. The design may also use isotactic layers on both sides of the syndiotactic layer.

**Polymerization process.** This process covers producing an alpha-olefin polymer, such as polypropylene, and treating the resulting polymer. After polymerization and recovery, the polymer is processed into granular or pelletized form. A hindered amine light stabilizer is oxidized to convert at least some of its amine groups into nitroxyl groups, then added to the polymer before it is heated and processed.

Career Highlights

Albe’s listed patent contributions address both the structure of polypropylene articles and the processing and stabilization of polymer products. Together, these inventions reflect work on improving material performance and supporting practical polymer manufacturing.
