Estimating the term…
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 mmφ, 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.
A process for preparing a modified thermoplastic resin comprising the steps of:
A modified thermoplastic resin composition obtained by incorporating at least one type of modifier-containing thermoplastic resin into the transport lines in a molten state for a continuously polymerized thermoplastic resin and subjecting the continuously polymerized thermoplastic resin and said modifier-containing thermoplastic resin to static mixing in said transport line and dynamic mixing for forceful kneading by external power, wherein the filtration pressure of the composition rate is no greater than the 10 kg/cm3/hr when filtration is performed using a double layer of 2400 mesh wire filters with an inner diameter of 64 mm, 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 filtration rate of 33.3 g/min.
