ABSTRACT:
There are disclosed a thermoplastic resin composition which comprises a styrenic resin comprising a modified styrenic polymer in which a compound having an unsaturated group and a polar group is bonded to the skeleton of a styrenic polymer having syndiotactic configuration (SPS) or to an end or an intermediate position of a substituent of the SPS, or the mixture of the above modified styrenic polymer and an unmodified SPS; and an inorganic filler, as well as a thermoplastic resin composition which comprises the aforesaid styrenic resin; and an other thermoplastic resin. The compositions are excellent in water resistance, impact resistance, heat resistance, modulus of elasticity and dynamical properties and capable of improving the adhesiveness to the inorganic filler or compatibility with the other resin without impairing the crystallization of the SPS and deteriorating the long-term heat resistant stability of the compositions.
