Letter

Polyamide 6 (PA6) is a semi-crystalline thermoplastic used in a wide range of engineering applications because of its attractive combination of good processability, mechanical property and chemical resistance. However, it has high moisture absorption and low resistance to crack propagation in the presence of a notch. Polymer blending is an efficient way to improve some deficient properties of these existing polymers, therefore, blends of PA6 with polycarbonate, polyphenylene oxide and glass microbead have been studied in some details. However, blending polyolefin and rubber elastomers such as styrene/butadiene/styrene copolymers, hydrogenated styrene/butadiene triblock copolymers, and ethylene-propylene-diene rubber with PA6 are the dominating approach to obtain high-toughed polyamide 6 materials [1, 2, 3, 4, 5, 6]. Because of the low elastic modulus of rubber elastomers, this kind of materials will distinctly decrease stiffness K resin is a styrene-butadiene copolymer with high...
