Abstract:
A styrene resin composition, comprising;(A) from 35 to 95% by weight of a styrenic polymer of which the melt index (MI, g/10 min) at 300Â° C. and under 1.2 kg is at least 8 and which essentially has a syndiotactic structure, (B) from 5 to 50% by weight of a polyethylene resin, of which <1> the melt tension (MT, g) measured at 290Â° C., through an orifice having a diameter of 2.095 mm, at a cylinder outlet speed of 6.2Ã—102 mm/min and at a take-up speed of 4.7Ã—104 mm/min, is from 0.3 to 10 and <2> the melt index (MI, g/10 min) at 190Â° C. and under 2.16 kg is from 0.1 to 10, and (C) from 0 to 15% by weight of a styrene-olefin copolymer having a styrene content of from 40 to 85% by weight, wherein the product of (a) the melt index (MI, g/10 min) of the styrene resin composition, measured at 300Â° C. and under 1.2 kg, and (b) the melt tension (MT, g) of the styrene resin composition, measured at 290Â° C. through an orifice having a diameter of 2.095 mm at a cylinder outlet speed of 6.2Ã—102 mm/min and at a take-up speed of 4.7Ã—104 mm/min, is at least 20.
