MODIFIED THERMOPLASTIC RESIN COMPOSITION AND METHOD OF PRODUCING THE SAME

摘要

A method of producing a modified thermoplastic resin composition comprising the steps of statically mixing a modifier-containing thermoplastic resin when it is added to a conveyor line of a thermoplastic resin, and dynamically mixing the mixture by passing it through agitation blades provided to the same conveyor line and through a dynamic mixer having power for driving them; and a modified thermoplastic resin composition prepared by this method having a filtration pressure rising rate of not greater than 10 kg/cm2/h when the resin is filtrated by two 2,400-mesh metal net filters having an inner diameter of 64 mm and superposed with each other at either a melting point of the resin or a temperature higher by at least 20 ~C than its plasticization point but lower than 100 ~C at a filtration rate of 33.3 g/min.
