titleOfInvention | Propylene resin composition |
abstract | A propylene resin composition which is a three-component material is improved in rigidity, heat resistance, and impact resistance while maintaining a satisfactory balance among these and further improved in low-temperature (about -30°C) impact resistance. A propylene resin composition comprising: n60-95 wt% of a crystalline propylene polymer ingredient (a) comprising a propylene homopolymer ingredient or a copolymer of propylene and up to 3 wt% ethylene or an α-olefin having 4-20 carbon atoms; and n40-5 wt% of a propylene/ethylene copolymer ingredient (b), n nwherein the ingredients are polymerized using a metallocene catalyst, and the composition satisfies the following properties i) to iv): ni) A melting point obtained by differential scanning calorimetry (DSC) is 156°C or higher, nii) A proportion of the copolymer ingredient (b) determined by a temperature rising elution fractionation (TREF) fractionating at three levels of temperature of 40°C, 100°C, and 140°C, is 5-40 wt%, niii) An ethylene content of the copolymer ingredient (b) determined by a temperature rising elution fractionation (TREF) fractionating at three levels of temperature of 40°C, 100°C, and 140°C, is 30-50 wt%, and an average ethylene content in components eluting at 40-100°C is 10 wt% or lower, and niv) The propylene/ethylene copolymer ingredient (b) comprises at least two kinds of propylene/ethylene copolymer ingredients (b-1) and (b-2), each of which differs in ethylene content, wherein an ethylene content of the ingredient (b-1) and an ethylene content of the ingredient (b-2) are 15-30 wt% and 40-55 wt%, respectively, and the ratio of the amount of ingredient (b-1) to that of ingredient (b-2), (b-1):(b-2), is in the range of from 1:99 to 40:60. |
