摘要： A process for preparing a modified thermoplastic resin composition by incorporating a modifier-containing thermoplastic resin into a transport line of a thermoplastic resin, comprising subjecting the resin to static mixing and to dynamic mixing by passing the resin through a dynamic mixing apparatus having a mixing blade unit and a power unit for driving the mixing blade unit and provided in the same transport line, as well as a modified thermoplastic resin composition prepared by the process and having a filtration pressure increase rate of no greater than 10 kg/cm2/hr when filtration is performed using a double layer of 2400 mesh wire filters with an inner diameter of 64 mm&phgr;, at a melting point of the modified thermoplastic resin or a temperature of from 20° C. to 100° C. higher than the plasticizing point of the resin and at a filtration rate of 33.3 g/min.
