Incorporating PLA to toughened PA۶/ SAN-g-PB blends without sacrificingthe mechanical and Impact Properties of Ternary blend

Commercialized PA۶/ABS blends (such as BAYER-INEOS Terblend® N) are highly toughenedblends with superior mechanical and Impact properties used in manufacturing of the automotive partsWhile substitution of non-petroleum base polymers with the petroleum one in order to lowering theconsumption of petroleum-based polymers according to new international environmental protocolsand standards, is a new novel approach that encourage us to make a new super-tough injection gradeeco-friendly PA۶/ABS/PLA blends without scarifying its superior mechanical and impact propertiesin comparison with commercialized PA۶/ABS. In this project Firstly, PA۶/SAN-g-PB binary blendswere prepared and flexural modulus, impact strength of these blends were compared with thecommercial grades like BAYER-INEOS Terblend® N. The best result was in Ratio of ۶۵/۳۵ wt.%of PA۶/SAN-g-PB then different loading of PLA incorporated in a way that the target properties staysin acceptable level. Maximum loading level of PLA without sacrificing the mechanical and ImpactProperties was about ۲۰ wt.% and the closest results to the PA۶/SAN-g-PB was in ۱۰wt.% .
