    • The present invention is directed to a process for producing a modified olefin polymer in an extruder having a feed zone, a melting zone, optionally a mixing zone and optionally a die zone, (A) introducing a stream of an olefin polymer into the feed zone of the extruder; (B) introducing a stream of a free radical generator directly into the feed zone or the melting zone or the mixing zone, if present, of the extruder; (C) introducing a stream of a functionally unsaturated compound directly into the feed zone or the melting zone or the mixing zone, if present, of the extruder; (D) extruding the mixture in the extruder at a temperature which is greater than the decomposition temperature of the free radical generator and the melting temperature of the olefin polymer but less than the decomposition temperature of the olefin polymer thereby producing the modified olefin polymer in the extruder; and, optionally, (G) passing the melt of the modified olefin polymer through the die zone to a pelletiser.
    • 本发明涉及在挤出机中制备改性烯烃聚合物的方法,所述挤出机具有进料区,熔化区,任选的混合区和任选的模区,(A)将烯烃聚合物流引入进料区 的挤出机; (B)将自由基生成物流直接引入挤出机的进料区或熔融区或混合区(如果存在)中; (C)将功能不饱和化合物流直接引入挤出机的进料区或熔融区或混合区(如果存在); (D)挤出机中的混合物的温度大于自由基发生剂的分解温度和烯烃聚合物的熔融温度,但低于烯烃聚合物的分解温度,从而在 挤出机中; 和(G)将改性烯烃聚合物的熔体通过模具区域通过造粒机。
