    Abstract: A composite film comprising at least one layer of a first plastic polymer and a substrate of a second polymer/first plastic polymer composition is prepared by intimately mixing about 15 to about 90 wt.% of first plastic polymer and about 10 to 85 wt.% of the second polymer, extruding the mixture through a film die while cooling at least one surface of the die outlet at least about 10oC below the melting point of the plastic polymer and cooling the film. In a preferred embodiment the first plastic polymer has a semi-crystalline or crystalline melting point which is at least 10oC above the softening or melting point of the second polymer. A sandwich type laminate comprising two outer skins of first plastic polymer enclosing a core comprising a blend of first plastic polymer and second polymer can be prepared by cooling both die outlet surfaces. Where a blown film die is utilized the inner and outer die layers must be cooled to accomplish this end. In a sheet die both the upper and lower die layers are cooled.

    Abstract: A polymer grafting process, apparatus and products obtained therewith are disclosed. The process comprises the melt-phase grafting of a polyolefin containing unsaturation sites with an enophile (such as maleic anhydride) under ene reaction conditions at 180 DEG -265 DEG C in reactor with a mean residence time of 12-40 minutes and a relatively narrow residence time distribution such that 90 percent of the reactor throughput has a residence time within 75-175 percent of the mean. The apparatus comprises means for supplying molten, pressurized unsaturated polyolefin and enophile, a distributively mixed reactor for receiving the pressurized, molten reactants, for maintaining the ene reaction conditions and for producing a grafted polymer product, and a finishing extruder for removal of unreacted enophile. The grafted polymer product contains ene grafted enophile, and has an intact molecular structure substantially unchanged from that of the polymer prior to grafting.

    Abstract translation: 公开了一种聚合物接枝方法，其中获得的装置和产品。 该方法包括在反应器中在180℃-265℃的反应条件下，在平均停留时间为12-40分钟的条件下，将烯不饱和位点的烯烃（例如马来酸酐）熔融相接枝到平均停留时间为12-40分钟， 停留时间分布使90％的反应堆吞吐量的停留时间在平均值的75-175％之内。 该装置包括用于供应熔融，加压的不饱和聚烯烃和亲油体的装置，用于接收加压的熔融反应物的分布式混合反应器，用于保持烯反应条件和用于生产接枝的聚合物产物，以及用于除去未反应的亲合子的精加工机。 接枝的聚合物产物含有接枝的亲核体，并且在接枝之前具有与聚合物基本上不变的完整分子结构。
