主 题:Nylon 6/polypropylene blends R-styrene-maleic anhydride copolymer ( R-SMA ) compatibilization morphology crystallinity properties
摘 要:The effect of R-styrene-maleic anhydride copolymer (R- SMA) compatibilzation on Nylon 6 ( PA6 )/polypropylene ( PP ) blends has been investigated experimentally through Molan test, microscopic morphology, and chemical structure. Results show that the moderate R-SMA addition can promote reaction between anhydride in R-SMA and amino in PA6, and lead to a new PA6-g- R-SMA copolymer in the blends. Such PA6-g-R-SMA eopolymer in the blends can effectively reduce the interfaeial tension and PP particle size, and improve the compatibility of two immiscible phases in the blends. The crystallinity of PA6 in PA6/PP blends has greatly decreased by PP blends. The blends have the best comprehensive mechanical and thermal properties when the mass ratio of PA6/PP/ R-SMA is 90:10:2 to 90:10:4. The impact strength of the PA6/PP blends with the eompatibilizer is increased by more than 150 %.
