Catalytic testing of Sn(IV) complexes for the formation of polylactide

Presenter(s)

Mayra Aguilar, Owen Paulson, Logan Nelson, and Shawn Hoglund

Abstract

Polylactide is a biodegradable polymer commonly used in medical applications, packaging, and textiles due to its environmentally friendly properties and ability to be produced from renewable resources. Coordination complexes of tin are conventionally used for ring-opening polymerization of lactide. Several tin(IV) complexes of the form Sn(β-diketonate)2Cl2 have been tested for their ability to catalyze the formation of polylactide with comparisons made to the industrially used, bis(2-ethylhexanoate)tin(II). The catalysts' performance was assessed by yield and NMR analyses.
