Research into the Preparation and Performance of PP-G-DL411 Compatibilizer and PP-G-DL411/GF/ PP Composites

Abstract:

Aluminum ester grafted polypropylene copolymer (PP-g-DL411) compatibilizer and PP-g-DL411/GF/PP composites are prepared by melting cross blend. FTIR results show that DL411 grafts on PP molecular chains and leads to a new PP-g-DL411 copolymer. SEM reveals that PP-g-DL411 can effectively improve the interface compatibility and enhance the interfacial adhesion between GF and PP. Experimental results indicate that the best comprehensive properties of PP-g-DL411/GF/ PP composites are achieved when the percentage of PP-g-DL411 is 8% and that of GF is between 40% and 45%. In particular the impact strength is increased by 222% compared with uncompatibilized GF/PP.
