Nylon 6/polypropylene blends%R-styrene-maleic anhydride copolymer (R-SMA)%compatibilization%morphology%crystallinity%properties
The effect of R-styrene-maleic anhydride copolymer (RSMA) compatibilzation on Nylon 6 ( PA6 )/polypropylene ( PP ) blends has been investigated experimentally through Molau 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-gR-SMA copolymer in the blends.Such PA6-g-R-SMA copolymer in the blends can effectively reduce the interfacial 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 compatibilizer is increased bv more than 150 ％.
