摘要： A continuous extrusion process for the functionalization of polymers through reactive extrusion. The process uses a continuous extrusion reactor comprising at least two sequential, very closely-coupled, independently driven screw extruders having a total effective length to diameter ratio greater than 60 to 1 and as high as 112 to 1 and providing greatly extended reaction times for efficiently producing a grafted polymer having a high level of functionalization. Drying of the polymer feed is performed in the continuous extrusion reactor. Multiple injections of reactants may be provided. Shear modification of the molecular weight 'of the grafted polymer is performed in the continuous extrusion reactor after the functionalization reactions. A continuous extrusion reactor and a grafted polymer having a high level of functionalization are also disclosed.

摘要： PURPOSE: A low-foaming construction interior part and a method for fabricating the same are provided to improve the workability and to prevent a transcription film from being easily released by mixing styrene-acrylonitrile to an ABS resin. CONSTITUTION: A 30-10 weight percent of styrene-acrylonitrile is mixed with 70-90 weight percent of an ABS resin in a mixer. Then, the mixture is dried at the temperature of 105°C(S1). Then, 0.2 to 0.9% of a foaming agent, 0.2 to 0.5% of citric acid, 0.02 to 0.2% of Zn, 0.06% of distributing agent, 0.2 to 0.5% of UV ray screen agent, and 0.2 to 0.5% of anti-oxidizer are mixed with the mixture(S2). While maintaining the mixer at the temperature of 110°C, the mixture resin is discharged from the mixer and introduced into a hopper(S3). Then, mixture resin fed from the hopper passes through cylinders so that the mixture resin has a gel type. In addition, gel type mixture resin passes through the second dice thereby extruding mixture resin foam(S4). After that, the mixture resin foam is cooled(S5).
