Publication number: 20230220164Abstract: A single vessel process for producing heteroleptic POSS compositions. The process involves the addition of two or more different organosilanes into a reactor containing a solvent. A base catalyst is added to the reactor to hydrolytically assemble the POSS cage core and statistically distribute the organic groups from the organosilanes around the periphery of the POSS cage core. An acid is then added to neutralize or quench the base catalyst. The product is washed and the remaining solvent is removed to recover the heteroleptic POSS. In some alternate embodiments, the product is filtered to recover the heteroleptic POSS. The heteroleptic POSS compositions produced by this process are able to provide an envelope of desirable effects. The heteroleptic POSS compositions may be used as additives for optimizing the performance attributes of coatings, biological materials, thermoplastics, thermoset, and gel polymer systems.Type: ApplicationFiled: March 10, 2021Publication date: July 13, 2023Applicant: Hybrid Plastics, IncorporatedInventors: Joseph D.
