PROCESS AND APPARATUS FOR THE DIRECT AND CONTINUOUS MODIFICATION OF POLYMER MELTS

본 발명은 개질되는 용융류에서 측용융류를 분리시키고, 이를 소정의 이축압출기에 공급시킨 후, 여기에 첨가제를 혼입하여 분산시킨 다음, 상기 첨가제 용융농축물을 개질되는 용융류와 역혼합시키므로써 폴리머 용융물을 직접, 연속적으로 개질시키면서도 유연성을 갖게 하는 방법 및 장치에 관한 것이다.

Zusammenfassung:	본 발명은 개질되는 용융류에서 측용융류를 분리시키고, 이를 소정의 이축압출기에 공급시킨 후, 여기에 첨가제를 혼입하여 분산시킨 다음, 상기 첨가제 용융농축물을 개질되는 용융류와 역혼합시키므로써 폴리머 용융물을 직접, 연속적으로 개질시키면서도 유연성을 갖게 하는 방법 및 장치에 관한 것이다. A process and an apparatus for the direct, continuous and flexible modification of polymer melts by branching off a branch melt stream from the main melt stream to be modified, dispersing the initially introduced additive in the melt in a specially designed twin-screw extruder, and subsequent recycling of the additive melt concentrate to the melt stream to be modified.
