With a total of 2 patents to his name, Czupski's work is recognized for its innovative approach to polymer production.

Latest Patents

Czupski's latest patents focus on methods for creating low-fluoride reactive PIB compositions. One method involves providing a modified C4 feedstock by blending a mixed C4 feedstock with a second feedstock that has a lower LB/IsoB ratio. The process includes feeding this modified feedstock to a continuous stirred-tank reactor (CSTR) with a homogeneous catalyst and polymerizing it while maintaining specific temperature and residence time conditions. The resulting purified PIB composition boasts a molecular weight ranging from 250 to 5000 Daltons and a fluoride content of less than 20 ppm.

Another embodiment of his patent emphasizes the use of isobutylene-enriched C4 feedstock, polymerized under similar conditions to achieve a low-fluoride product. This innovative approach not only enhances the quality of the PIB composition but also addresses environmental concerns related to fluoride content.
