Toward an alternative compatibilizer for PLA/cellulose composites: Grafting of xyloglucan with PLA

► Xyloglucan grafted with PLLA chains via ring-opening polymerization. ► Moisture uptake of xyloglucan decreased. ► Lowered glass transition temperature of native xyloglucan. ► Candidate material as a compatibilizer in cellulose/PLA composites.
