Investigation of PLA composites modified by butadiene rubber using the compatibilization method
Application of biodegradable polylactic acid (PLA) is limited by its poor toughness and processability. This research focused on modifying PLA using butadiene rubber (BR) and epoxy butadiene rubber (EBR) as a toughening material. To enhance the compatibility between PLA and BR, a...
