In this study, poly(4-pinacolatoborylstyrene) (PB) was synthesized and used as a macromolecular cross-linker for cellulose acetate (CA), which successfully improved the mechanical and rheological properties of CA without sacrificing transparency. Moreover, the obtained CA materials could be recycled via solution reprocessing without significant decrease of mechanical properties.
Cellulose acetate (CA) is an important group of polymeric materials that have found broad applications. However, the narrow range of processing temperature causes difficulties to improve the mechanical properties of CA. In this work, poly(4-pinacolatoborylstyrene) (PB) was synthesized and employed as a macromolecular cross-linker for CA. Due to the dynamic coordination interaction between the boron center and hydroxyl groups on PB and CA, respectively, CA samples could be easily handled via the solution processing method. The addition of macromolecular PB additives (2.5 wt%) have successfully enhanced the mechanical properties, rheological properties of CA without losing the transparent appearance. Furthermore, the obtained CA materials could be recycled via solution reprocessing without apparent decrease of the mechanical properties.
