Abstract
There are disclosed a polystyrene composition which comprises 100 parts by weight of a syndiotactic polystyrene (SPS)(a) and 1 to 100 parts by weight of a high molecular compound comprising 5 to 95% by weight of polyphenylene ether (PPO) and/or modified PPO and 95 to 5% by weight of a rubbery elastomer (b) and optionally, 1 to 350 parts by weight of an inorganic filler (d) and also a polystyrene composition which comprises 100 parts by weight of the component (a), 0.1 to 30 parts by weight of the component (b) and 1 to 100 parts by weight of a rubbery elastomer (c) and optionally, 1 to 350 parts by weight of the component (d). The above compositions are greatly improved in impact resistance, elongation and retention of physical properties during recycling without detriment to heat resistance and modulus of elasticity.
